    Yes, you can use the Mach3 software on a CNC Masters Mill, but you will need to replace the main controller card with one of the following:

    Our breakout board (works with Mach3 and LinuxCNC and requires a parallel port on your computer):

    Generic USB breakout board (works with Mach3):
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    This board will need to be connected to the drivers for each stepper motor. From my research, these mills have gecko drivers to drive the individual stepper motors.

    It has also been noted with the power supply may be under powered as well. If you feel that is the case, you may want to consider replacing that as well.

  • HI..I am having a problem with my machine going off axis and not returning to zero

    Hi, can you elaborate on what you mean off axis? If the CNC router is milling correctly and then suddenly in a location that you would not expect, then you are exceeding the torque of the stepper motors and stalling. If the cnc router stalls, then the cnc router will continue but the software controlling the cnc router will not have the correct position of the cnc router.

    If this is the case, then you need to either reduce the acceleration, reduce the velocity, or both. Does the problem occur during the milling process or during the jogging (rapids)?

  • What are the noise levels of the 1.5 Kw and 2.2Kw spindles?

    The noise level of the 1.5 kW and the 2.2 kW are very similar. The noise level is considerably quieter than typical routers. I am going to add sound db levels to this FAQ a bit later.

    Additional Information:
    The db (decibels) reading for the spindle is 70 and an 890 Porter Cable router (a lower powered tool than the spindle) measured 90 db. Both measurements were taken in the same environment and measured at the same distance from the tool.

  • Hello what is the thread size of the water cooling fittings on the 2.2kw spindle? I am wondering if I can replace the fittings with standard pc liquid cooling fittings, which are G1/4".

    They do have a similar looking thread as the G1/4”, but I will confirm in the morning. We use the G1/4” on the pump and radiator so it will be easy to determine this fit when I get into the office.

  • Hello I bought a full setup of parts a couple years ago to make a cnc router and now I have decided that I want to make a cnc router/plasma. I was wondering how to go about hooking up the plasma to the breakout board

    Does your plasma cutter have an external trigger that voltage can be applied to make the trigger engage? If I known, please provide the brand and model of your plasma cutter so we can determine this.

    Additional Information:
    I converted my blackToe to do plasma cutting. Used the Motor control relay on the break out board and just wired it into the plasma cutter trigger. Put a large pan (like a car oil drip pan) with about 1/4 inch of water on the table and attached fixtures. 400 15ga parts later it's still working great.

    Additional Information:
    That is so cool!!

    Hello I bought a full setup of parts a couple years ago to make a cnc router and now I have decided that I want to make a cnc router/plasma. I was wondering how to go about hooking up the plasma to the breakout board

  • I was referred to your company by a friend who uses your products and i notice you have finance / lease options, are these available to people outside the United States? Im located in Canada
  • . I purchased the 5x Greembull recently and was hoping I could get some advice and/or plans for the torsion box and table

    A torsion box is a way to create a dead flat surface for the CNC router. A torsion box consists of an internal grid of wood that serves as the structure and a top and bottom layer sandwiching the internal grid layer.

    Here is an excellent resource on how to make a torsion box.

    Make sure to leave 2 inches or more overhang on the top layer (3/4" thick) to make room for the rails and the chain mounts.

  • WHAT CAUSES ONE OF MY TWO AXIS MOTORS TO STOP WHILE THE MACH3 PROGRAM IS STILL RUNNING

    If one of your stepper motors decides to stop moving and the others are moving during a CNC milling or laser cutting job, then there could be two things that could be causing this.

    - The motor found its limiting torque (usually comes with a not-so-pleasant sound). This is where the control software is trying to move the stepper motor too fast (velocity, or too fast too quickly, acceleration) and the load against the stepper motor (inertia of the machine, or the material against the end mill while milling). Recommended action is to lower the velocity and/or acceleration, and/or lower the feedrate when cutting.

    - There is a wiring issue with the wiring from the driver to the motor. This could be a loose wire, or a chafed wire (or two shorting together). It can also be a loose digital wire from the controller board to the driver. Sometimes wire ties can be the culprit. Recommended action would be to thoroughly inspect the wiring.

    It's probably not the limit switches since that would cause a stop to the entire motion of the cnc router or laser machine.

    Sometimes Mach3 will show a status when something goes wrong, but in cases where the motor is stopping due to its torque limit, then that would not be shown in the status. It's always good to check it anyway.

    Additional Information:
    I need to clarify my situation a little better after going to my shop and trying to run another program on Mach 3. About 15 minutes into the milling process all the motors (2-X axis, Y axis and Z axis)stop but the program continues to run. I stop the program and after a couple of minutes when I try to restart the program all the motors start working again. Then after another 15 minutes or so, all the motors stop again. I checked and rechecked my wiring. This has never happened to me before when running the same programs with the same setups and motor speeds. All of a sudden when I reloaded a program I successfully used before it does this. Do you have any recommendations?

    Additional Information:
    Yeah, it sounds like a more complex issue. Have you tried running in the air without using the spindle. This may be a power related issue.

    Additional Information:
    That's exactly what I did. I ran the program without the router motor on just to see if the motors would get through the whole program but they stopped working after about fifteen minutes and then I was able to start them again after about 3 or 4 minutes. I never had this problem before so you can imagine my frustration especially after ruining a couple of projects on expensive material.

    Additional Information:
    Sure. I can completely understand. Try this: disconnect all but one of the driver from power and digital connection and do the air run. Repeat this for each driver and note your findings. This will rule out the drivers causing a power failure.

    Also, is your stepper motors and drivers on a separate power circuit from the computer?

    Additional Information:
    I will try disconnecting each driver and digital connection, which will be a real pain because it will be hard to access.

    All the stepper motors, drivers and computer are plugged into the same power strip.

    Additional Information:
    Ok, so there is no power failure going on, but I believe it is necessary to test each stepper motor and driver pair individually. Hopefully that will lead to a conclusion.

    Additional Information:
    It will take a little time but I will do it and report back on my findings.

    Additional Information:
    Curious, what machine is exhibiting this problem?

    Additional Information:
    I purchased a BYCNC kit back in 2009 with an approximate cutting area of 2' X 4'. I later changed out the Z-Axis Motor and controller for a larger one and have two X-axis motors and controllers. In 2010 I rebuilt the machine out of birch plywood instead of the particle board that the kit supplied. I sent Patrick pictures to him. The machine never gave me a problem till now.

    Additional Information:
    Thanks for the update. This is Patrick by the way. I answer pretty much all of the Customer Service questions. That machine has given quite a good history.

    Additional Information:
    I love the machine and made a number of samples of my work for my e-commerce site, but I can't start selling product until I know this problem is solved because I will not be able to fulfill orders. I finally got all the electronics out of its enclosed protected area near the machine so that I test each controller as you recommended. I hope the problem can be rectified. Will let you know.

    Additional Information:
    Thanks.

    Additional Information:
    I tested each stepper motor and driver pair individually and they worked so what might be the next step?

    Additional Information:
    Did each stepper motor driver pair work for the full +15 minutes?

    Additional Information:
    Yes, I had them in operation for over 30 minutes.

    Additional Information:
    Ok, well it’s good that the motors and driver are ok. We are now down to the power supply and the breakout board as possible causes for the stop. I have a feeling it may be the power supply where with all three drivers drawing current and the power supply maybe getting too hot. Is the fan in the power supply working? You can also test to see if there is 36 volts on the power supply voltage output (V+ and V-).

    Regarding the breakout board, if you have an oscilloscope, you can test if the driver pulses are outputting, but I would consider this as a last resort after you determine if there is a problem with the power supply.

    Additional Information:
    I tested the power supply with a voltmeter and each output was registering 39-40 volts. I think the problem may be the g-code. I am using V-Carve pro to do design and output to Mach 3 Mill g-code. When I studied the g-code lines I noticed that further into the program the z-axis g-code stopped zeroing out to move to the next part of the carving. In other words both the x and y keep moving and the z just stopped working because there was g-code missing. I think something is missing when the design was converted to g-code. I noticed that when I ran a simpler project it worked without problems so I need to investigate this further.

    Additional Information:
    New Update, Its not the g-code. I started to run the long program and everything was working fine until about 45 minutes into it, all the motors stopped working (but the program was still running) and there was a high pitched hum. When I put my hands on the motors they were all trying to move but it seemed they were all stalled. I turned the power off, gave it a minute and when I turned it back on I was able to move the motors again. Could this be a power supply problem?

    Additional Information:
    It does sound more and more like a power supply problem. Did you test the power supply after the motors stopped?

    Additional Information:
    No, I did not. What should I be looking for.

    Additional Information:
    It’s good that you know the voltage during normal operation, so you have a base understood. If the power supply is the problem, the voltage will be reduced or non existent when measured after the problem.

    Additional Information:
    Also, check to see if the fan is running on the power supply when the motors stop. That may (not absolutely) be an indication.

    Additional Information:
    I'll run another test, check the voltage and fan when the problem occurs and let you know. Thanks for hanging in there with me as we try to resolve the problem.

    Additional Information:
    It’s my pleasure. This service is rarely used and is faster then email. Odd nobody uses it. Any recommendations you can give would be great. No problem using this FAQ to pose ideas as this resolution will be cleaned up later.

    Additional Information:
    It might be that people do not realize you can communicate through the sight like this because they are so used to e-mail and texting. You may want to explain this feature in the customer service section.

    I ran the program this morning and it did not take long before the motors stopped. While operating the voltages for all three motors was 46 volts, when the motors stalled (and again there was a high pitch hum) the voltage went up to 60 volts and the fan on the power supply was operating.

    Additional Information:
    So, the driver work individually, but not all together. There is a high pitch sound when the motors fail. You have noted 60 volts from the power supply and the supply fan remains on. This is a difficult issue to resolve, but it seems to me that your power supply may be bad. The 60v measurement tells me that the current dropped and ohms law tells us that is current drops, volts will rise if the resistance stays the same.

    Additional Information:
    As one last test I am going to test each driver again and let them go through the entire program because it seems that the failure can occur at the beginning or towards the end of the program. When I originally tested ach driver I let them run for about a half an hour and the program takes over an hour to run completely. I just want to make sure that it is not the drivers. I will report back when I finished but as you noted it may be the power supply but I want to make sure.

    Additional Information:
    That’s a great idea.

    Additional Information:
    I just ran the x-axis through the whole program and there was no problem especially since I have two NEMA 23 motors moving that axis. Before I check the Y and Z could having a NEMA 34 on the Z axis with appropriate controller be a problem. I used the larger motor on the z axis because the router I am using is a large 1 1/2 hp. I've run this program in the past with this set-up and have not had a problem.

    Additional Information:
    Having a, say 3.0 amp driver, driving a stepper motor that typically requires a 6 amp driver would not seem to be an issue since the driver is limiting the current draw, but the driver may not be able to handle larger coil and back EMF with the protection on the 3.0 amp driver. With that said, I don’t believe that is the issue in this case.

    Additional Information:
    I don't either because I was able to run this and other complicated programs with this set-up in the past. I will let you know on the y and z axis.

    Additional Information:
    Thanks

    Additional Information:
    I ran the Y axis and z axis separately through the entire program and there was no stopping or problem. I guess the culprit is the power supply and I'll order a new one and hope that resolves the problem.

    Additional Information:
    Yes, that is the most probable cause. Please keep me informed. Thanks!

    Additional Information:
    Received and installed the new power supply. I ran the program with the router on and it worked flawlessly. The program runs for an hour and a half and I did not have a single problem. I guess it was the power supply but I was glad to go through all the diagnostics we discussed before replacing it. I hope this power supply lasts a lot longer than the last one. Thanks much for hanging in there with me and coming up with the solution.

    Additional Information:
    It’s my absolute pleasure and I am so happy to hear that the power supply replacement solved the problem.

    WHAT CAUSES ONE OF MY TWO AXIS MOTORS TO STOP WHILE THE MACH3 PROGRAM IS STILL RUNNING

  • I have your breakout board with relay parallel port , I have a vacuum, light on router and air pump I want to also hook up to board, can I hook those up to board and also could I had reylays to each one, what is the best way to figure this out any information would be great. Thanks

    Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit.

    See this image of a similar connection. The terminal has the same connections.
    https://www.buildyourcnc.com/images/vacuum-pressure-controller-relay-terminals-700.JPG

    Image of the relay terminal:
    https://www.buildyourcnc.com/images/breakoutboardrelayNONC.PNG

    The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router.


    Additional Information:
    You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

    Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.

  • USING MACH3, MY MACHINE STOPS IN THE MIDDLE OF A PROJECT. HOW CAN IT BE STARTED AGAIN FROM POINT STOPPED?

    Dealing with a mid-stop cut via Mach3, you will have to be careful if it is intentionally or unintentional. If you desire to stop your machine while in the middle of a cut be sure to stop it when the machine is moving in an upward motion on the z-axis and the X/Y-axis are stationary. Then you can choose the point (G-code) where the machine was left off and click on the Run from here button on the Program Run screen (left hand side) right above the Reset button.
    (Make sure spindle/router is running before hand!)

    Now if the machine stops unintentionally, and was moving in either the X/Y-axis, then it will be difficult to run the machine from the original point dealing with the coordinates might have been lost due the the machine continuing motion but via Mach3 the machine has stopped.

    If this occurs to fight this issue before hand, is marking your home with the spindle/router to make a hole were your home is. Although moving it manually back to home the machine can be off by the smallest amount and could cause an inconsistent cut. If accuracy is something that can not be risked, then you can home the machine about a 1/4" or 1/2" down from the original home to start your cut on the same material but loosing that small piece.

    Additional Information:


    Additional Information:
    My typical go to solution is:

    - Note the current g-code line where the machine stopped.
    - If Mach3 errored and you cannot control the machine, Exit Mach3 - you may find that reset, stop does nothing to stop the spindle. When you exit mach3, the spindle will stop automatically.
    - Restart Mach3. The DRO (Digital Readout) should show the correct coordinates where the machine position was before exiting Mach3.
    - Scroll to the g-code line where the machine stopped. You may need to go a few lines prior to make sure you are not skipping any machining operations (which is why it is a good idea to learn the basics of g-code - don't worry, it's easy)
    - Click on the "Run from Here" button.
    - Mach3 will present you with a "Preparation Move" dialog box with the location that it will move to. If the coordinates shows a position that is into the material, make sure to specify a rapid height (clearance height) so the machine will move up first and then move to the location before moving down into the material. If the spindle is automatically controlled by Mach3, make sure to check the turn spindle on checkbox. If not, make sure the router or spindle is on before clicking OK.

  • Mach3 status showed PWM Bumped to Minimum Setting. The CNC machine stopped

    If mach3 displays a message in the status line with "PWM Bumped to Minimum Setting" and the CNC router or CNC machine stopped in the middle of the milling, you will need to do the following:

    Also, check to see if the fan is running on the power supply when the motors stop. That may (not absolutely) be an indication.

    Additional Information:
    I'll run another test, check the voltage and fan when the problem occurs and let you know. Thanks for hanging in there with me as we try to resolve the problem.

    Additional Information:
    It’s my pleasure. This service is rarely used and is faster then email. Odd nobody uses it. Any recommendations you can give would be great. No problem using this FAQ to pose ideas as this resolution will be cleaned up later.

    Additional Information:
    It might be that people do not realize you can communicate through the sight like this because they are so used to e-mail and texting. You may want to explain this feature in the customer service section.

    I ran the program this morning and it did not take long before the motors stopped. While operating the voltages for all three motors was 46 volts, when the motors stalled (and again there was a high pitch hum) the voltage went up to 60 volts and the fan on the power supply was operating.

    Additional Information:
    So, the driver work individually, but not all together. There is a high pitch sound when the motors fail. You have noted 60 volts from the power supply and the supply fan remains on. This is a difficult issue to resolve, but it seems to me that your power supply may be bad. The 60v measurement tells me that the current dropped and ohms law tells us that is current drops, volts will rise if the resistance stays the same.

    Additional Information:
    As one last test I am going to test each driver again and let them go through the entire program because it seems that the failure can occur at the beginning or towards the end of the program. When I originally tested ach driver I let them run for about a half an hour and the program takes over an hour to run completely. I just want to make sure that it is not the drivers. I will report back when I finished but as you noted it may be the power supply but I want to make sure.

    Additional Information:
    That’s a great idea.

    Additional Information:
    I just ran the x-axis through the whole program and there was no problem especially since I have two NEMA 23 motors moving that axis. Before I check the Y and Z could having a NEMA 34 on the Z axis with appropriate controller be a problem. I used the larger motor on the z axis because the router I am using is a large 1 1/2 hp. I've run this program in the past with this set-up and have not had a problem.

    Additional Information:
    Having a, say 3.0 amp driver, driving a stepper motor that typically requires a 6 amp driver would not seem to be an issue since the driver is limiting the current draw, but the driver may not be able to handle larger coil and back EMF with the protection on the 3.0 amp driver. With that said, I don’t believe that is the issue in this case.

    Additional Information:
    I don't either because I was able to run this and other complicated programs with this set-up in the past. I will let you know on the y and z axis.

    Additional Information:
    Thanks

    Additional Information:
    I ran the Y axis and z axis separately through the entire program and there was no stopping or problem. I guess the culprit is the power supply and I'll order a new one and hope that resolves the problem.

    Additional Information:
    Yes, that is the most probable cause. Please keep me informed. Thanks!

    Additional Information:
    Received and installed the new power supply. I ran the program with the router on and it worked flawlessly. The program runs for an hour and a half and I did not have a single problem. I guess it was the power supply but I was glad to go through all the diagnostics we discussed before replacing it. I hope this power supply lasts a lot longer than the last one. Thanks much for hanging in there with me and coming up with the solution.

    Additional Information:
    It’s my absolute pleasure and I am so happy to hear that the power supply replacement solved the problem.

    What causes one of my two x-axis motors to stop while the Mach 3 program is still running?

  • what causes one of my x-axis motors to overheat.

    What can cause a stepper motor to overheat can be related to a few things. First, it good to know that stepper motors will normally be hot to the touch and you should not worry about this. There is a ton of current running through the coils of a stepper motor, and current will cause heat to build up.

    Energy comes in many basic forms: movement, heat and light. Stepper motors don't produce light, so we can rule that out, so you have movement and heat. When the stepper motor is not moving, the current is still trying to make sure the stepper motor is holding its position and since movement is not a factor here, heat will build up.

    If the heat worries you, you can keep the cnc machine moving, or turned off. There will still be heat when moving, but not all of the current is being used as heat. You can also consider lowering the allowable current draw using the stepper motor driver's dip switches.

  • I have a "Based on planet-cnc's diy cnc usb controller", I activated the output signal (mist, coolant or spindle) in the planetcnc software but at the output there is no voltage, what can I do to turn on this elements?

    On the Planet-CNC board, the Mist, Spindle and Coolant outputs will require a relay to switch on those devices. Test one of those terminals with a multi-meter (Mist, Coolant, or Spindle). Each of these terminals have a GND next to the terminal for the device.

    Test the voltage across the GND to the terminal with the arrow that you want to test. Go to the software and click on the device you want to test (mist, coolant or spindle) and note the voltage. If no voltage is output then check under the board to where the terminals are soldered. Re-test the terminals across the solder joints rather than the terminal block wire inputs. If you get a voltage, then there is a problem with the terminal block. If you don't get a voltage, then the board is not functioning properly.

    Additional Information:
    I activated the output signal.. I did the tests indicated and I did not get voltage. I heated the welds of the three outputs and now works coolant but no mist or spindle, what should I do?

    Additional Information:
    There are probably cold joints on the board at the chip or the resistors on the traces for those terminals. You can send the board back to us and we will repair and test the board.

    Additional Information:
    If you want to troubleshoot this yourself, take a very close look at the traces from the terminal and follow them to the tiny resistors, then to the legs of the chip. If you see any bad or bridged solder joints, then those will need to be re-touched. It will take a somewhat experienced soldering individual to accomplish this task and will require flux to make sure the solder joints are fully joined.

  • Mach3 stopping while cutting, no programmed pause or stop.

    On the Mach3 main screen (program run tab), is there a status message when the Mach3 and machine stops?

    Additional Information:
    We didn't look, we don't experience a lot of problems. Are those messages stored in a cache file ?

    Additional Information:
    I don't believe there is a log associated with the status messages (in my brief research). There should be, definitely.

    Next time this happens, check out that message.

    You may find that the limit switch was triggered from some interference from the motors or other EMF source. If that is the case, then you will need to do the following:
    - Use shielded cable for the limit swtches
    - Reorganize the limit switch cables far away from the motor cables
    - Adjust the debounce parameter for the limit switches within Mach3

    Additional Information:
    I am embarrassed to say we don't have limit switches installed. It does share power with other machines, like a table saw and a big dust collector.

    Additional Information:
    Well, for personal safety, the machine will not be able to break through the extents of the machine, so you are fine.

    The limit switch triggering is the only thing I can think of that would stop Mach3. I would love to know the status message when it happens again. Just for fun, check the inputs section of the "ports and pins" dialog and make sure all of the inputs (that you are not using) are disabled, so they don't act as antennae.

  • my end mills (router bits) are breaking during my cutting or milling process

    Broken end mills are generally a function of the end mills getting too hot, so it is a good practice to check your feedrates and depth per pass to make sure your end mill is not getting hot. After a small job, touch the end mill immediately after the spindle stops (or use a device that can measure the temperature). If it is hot to the touch, then you probably need to increase the feedrate and decrease the depth per pass. Increasing the feedrate will cause the end mill to mill new "cool" material faster, thereby keeping the end mill cool. Reducing the depth per pass will allow the end mill to acept this faster feedrate and maintain your desired edge finish.

  • Can I make my feedrates faster by changing my lead screw?

    Changing your lead screws from a tight to a lose lead will definitely make your machine move faster as long as your stepper motors can handle the new torque that the lead screws will impose.

    Here is an example of a speed change from one lead screw to another:
    - Existing constants in the example: Stepper Motor steps 200, microstepping 1/8 making the total steps 200 * 8 = 1600.
    - Old lead screw: 1/2" allthread = 13 threads per inch (UNC)
    - New Lead Screw: 1/2" 5 starts, 10 TPI = 10 / 5 = 2 turns per inch

    Old lead screw would achieve a steps per inch of:
    1600 / (1 inch / 13 turns) = 20,800 steps per inch (You can also express the calculation as 1600 * 13 = 20,800 steps/inch)

    New lead screw would achieve a steps per inch of:
    1600 / (1 inch / 2 turns) = 3200 steps per inch

    You can see that the new lead screw requires far fewer steps to get to the same length of travel. If you maintained the same velocity for both examples, the new lead screw would travel the same distance 13/2 = 6.5 times faster. So, if your velocity was say 10 ipm, your new velocity would be 65 ipm. That would translate to far fewer burned edges and longer end mill life!

    Just remember, confirm that your motors will be able to handle the new lead screw. You will need to reduce the steps/inch causing the motor torque to increase quite a bit, so you should be fine.

  • Can i wire my drivers and motors in parallel to your laser controll system to add a laser unit on my router?

    It is possible to add the laser control system to an existing CNC router but there are a few considerations:

    All of the signal wires from the laser controller that connect to the drivers drivers and all of the signal wires from the CNC controller that go to the drivers will need to first pass through a tri-state gate buffer chip that will allow one set of signal wires to be switched off and the other set switched on.

    We have a board that does this in development, but If you wish to accomplish this on your own, you will need:

    - 3 Quad buffer line drivers (each one can receive 4 signal wires): https://newbiehack.com/categories/newbiehack-integrated_circuits-buffer-quad-buffer-line-driver-throughhole
    - Some perf board, solder and a soldering iron, and some hookup wire.

  • With the Mach3 USB board, my stepper motors are moving or spinning slowly.

    If your motors turn very slowly using your Mach3 USB board, then either the pulse from the board is being output at a slow rate or the motor drivers are set to a higher than expected microstepping:

    The Mach3 USB board outputs the pulse rather than the computer, but Mach3 controls this pulse frequency within the motor tuning section. First, determine if the travel distance is correct with the computer and the physical travel of the machine.

    If the travel is different, then your stepper motor driver's microstepping is incorrect, or the steps per inch/mm in the motor tuning within Mach3 is incorrect.

    If the travel is correct, then simply change the velocity and acceleration parameters to your desired level. If Mach3 will not achieve the velocity you desire, then decrease your stepper motor driver's microstepping setting, readjust the step per inch/mm in mach3 and readjust the acceleration and velocity to your desired levels.

  • Mach3 USB interface board. Could you please give me the correct wiring configuration for tool prob?

    Depending on the probe that you have, you should have two wires coming from the probe. One of those two wires will need to be connect to an input pin as shown in this wiring diagram (the diagram show the probe connected to pin I4):
    https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf

    The other pin is connected to V-. Please make sure that you have 24V connected to the V- and V+ on that side of the Mach3 USB board.

    The way the probe works is when the probe is in contact with an object, a specific spring mechanism will cause the input pin to be connected to the V- (close the circuit). When Mach3 senses an active low on the input pin, mach3 knows that the probe has made contact (closed the circuit).

    If your probe is used as a Z-Axis zero plate, then the concept is the same, but the end mill is connected to V- and the plate is connected to the input pin. If the plate comes in contact to the end mill, then the circuit is closed and mach3 will sense an active low on the input pin.

  • limit switch triggered in mach3

    http://buildyourcnc.com/PrimeronHomingandLimitSwitches.aspx
    There is a pin setting in Mach3 that says how to react to the inputs from the switches. Your setting is probably wrong as the trigger happens immediately.

    You may want to think about shielded wire and/or a resistor on each limit switch line. If there are stray wires, connect them to ground. Additionally, the shield from the shielded cable insulation should alse connected to ground at both ends.
    Try upping the Debounce interval in Mach3. You have to adjust the debounce interval. You go to config,general config, and it is in the top right corner. I set mine to 100 and it seems to work well.

  • metal cutting

    Yes, the greenLean can cut metals such as aluminum and brass. The gantry and Y carriage was designed to be rigid enough to handle these types of metals. The typical metal cutting techniques should be used, such as high feedrates to reduce heat buildup at the end mill, or the use of cutting fluids or cold air used at the end mill as is necessary with most machines that cut similar metals. This is necessary since the aluminum has a rather low melting point and can clog the end mill.

    Additional Information:
    All of our machines are capable of cutting many metals, including steel and aluminum as long as the proper CNC machining operations are used like light fast passes, and if desired, using air cooling for better performance.

    Here is a video of one of our customer demonstrating aluminum cutting using air to cool the end mill.

  • What is the micro-stepping value of the STB4100?

    The Mach3 USB (STB4100) doesn't actually control the microstepping. Each stepper motor driver that connects to the stepper motor had a dip switch setting that you can change your microstepping value.

    The motion cars simply outputs the number of step pulses that you specify from the computer's control software. For example, if you set the stepper motor driver to move 1 inch with 1600 steps (let's say, the microstepping is 4 for simplicity and is set on the stepper motor driver), the computer's software would tell the motion card to deliver 1600 steps to the driver. The driver then moves the motor accordingly. If you change the stepper motor driver's microsteps to 2, but you maintained the 1600 steps from the computer control software, then the stepper motor would move 2 inches instead of 1 inch.

    I hope this helps with your microstepping question related to the cnc motion card. Just remember to modify the steps/inch or steps/mm setting in your CNC control software and it corresponds to the setting on the stepper motor driver.

  • how to conect the VFD spindle using modbus

    It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol.

    The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

    You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

    Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

    You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
    - PD001 - value 2 - Enables with communication aspect of the VFD
    - PD002 - value 2 - Enables frequency control from the communcations port
    - PD163 - value 1 - VFD address
    - PD164 - value 1 - Baud rate of 9600 (speed of the communication)
    - PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

    Copy the dll file to the PlugIns folder of mach3.

    Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

    Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

    No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

    Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

    You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.

  • I've been unable to cut through acrylic or wood at a thickness of 1/8" or less with the BlackTooth. Even with multiple passes (x10) and full power, a clean cut cannot be accomplished. Based on videos I've seen something doesn't seem right. I noticed that the nozzle gets very warm, almost untouchable during even short runs.

    Since the nozzle is getting warm, much of the laser energy is not exiting the aperture and is hitting the inside of the nozzle. You need to align the laser's final mirror to direct it out of the nozzle's aperture and you will have more than enough energy to cut 1/8" acrylic efficiently.

  • I am converting from a Parallel Port to the Mach3 USB. My limit switches can accomodate up to 5VDC and I want to Drive a Relay from one of the outputs. Will my switches work and do I need a 24VDC Relay?

    Yes, the best way to attach a relay to the output of the Mach3 USB board is to use an SSR (Solid State Relay) at the 24 Volt rating. This is the standard supply for this side of the Mach3 USB board.

  • I have the 2.2KW VFD. I would like to have it controlled through software. What are the Mode parameters that need to be changed that will allow FWD/ REV, START/STOP and RPM control?

    What controller are you using to control the cnc machine (Mach3 usb, parallel breakout board, etc.)?

    The spindle VFD has an input for 0-10 volts to control the speed and can be used with the MAch3 USB or the Pokeys57CNC board. There are also other terminals in the VFD to control the forwared/reverse and start and stop. Mach3 has parameters to control these output and you need to specify which pins are used for these.

    You can also use the TX/RX RS-485 connection on the VFD to have total control using an FTDI USB to serial connector board to connect the computer directly to the VFD.

  • Hello, My friend has purchased the Redfly and I am helping him a little with it. We are both very new to CNC. I am using fusion 360 at the moment. This can tool path and create gcode. I was wondering if Mach 3 or similar is still needed. Is there a tutorial you could point me to that explains how to get the Gcode from the PC, via Serial to the Redfly?

    Fusion 360 is a program that allows you to design in a parametric 3 dimensional environment and also provides a great CAM toolset. Fusion 360 will produce the gcode with the CAM capabilities. The gcode is used to move the machine in various ways in order to mill the material; however, software is needed to interpret this gcode and cause the machine to move according to the gcode instructions. This is called control software. So Fusion is CAD/CAM, and you still need "control". Mach3 is one example of control software for milling and is highly recommended.

    Install Mach3 onto the computer that will connect to the redFly(CNC electronics), then configure the Mach3 parameters for the machine (motor tuning, plug-ins, inputs/output, etc.). Home the machine, load the gcode into Mach3 and the machine will move according to the gcode.

    A word of caution, since you are new to CNC machines, make sure you familiar yourself with the machine and the movements of the machine specific to how the gcode is arranged with respect to the coordinates of the machine. Try with very simple gcode until you get a very good understanding of how the machine will move.
