  • machine wont zero machine coordinates

    The machine coordinates depicts the actual machine location and not the logical location for one of the G55, 56, etc. work offsets. If you need to zero the actual machine's coordinates, then you need to select the settings tab, click on the "reset interp" button at the lower right of the screen and zero each axis of the "encoder position" section. To reflect this value to the main digital readout (DRO), click on the "to DRO" for each axis.

  • This question has been asked before: What happened to my Mach3 Motor Tune-up in the Configure tab, it has disappeared but had been there before. The previous answers were to go to config: motor tuning

    Motor tuning is the third option down when you click the config menu option. I have never used the motor tuning dialog from anywhere else. If you are looking for the button to calibrate the axes, then go to the settings tab and click on the button that says "Set Steps per Unit".

  • This question has been asked before: What happened to my Mach3 Motor Tune-up in the Configure tab, it has disappeared but had been there before. The previous answers were to go to config: motor tuning

    The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

    Additional Information:
    I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

    Additional Information:
    Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

  • how do I control coolant mist using the mach3usb break out board

    You will need a 24V relay controlled by one of the output terminals of the Mach3 USB controller. You can see a video that demonstrates the use of the output pins for this controller and how a relay is connected to the output terminal and the power supply. It is the video that is titled "Mach3 USB Controller Outputs"

  • Does Mach3USB have a selection for motor tuning, if so, where, the selection in the config menu doesn't work

    The motor tuning for any controller under Mach3 is independent of the actual controller. It is actually a function of the steps per unit and setting the velocity which is units/minute and acceleration which is units/minute/minute.

    To adjust the velocity, acceleration and steps/unit, click on config -> motor tuning.

  • How can I connect an inductive proximity sensor to the Mach3 USB controller?

    I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

    The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

  • the breakout board that i recieved has both a 25pin and usb connections. can i use the usb to plug into my laptop

    A parallel breakout board requires a computer with a parallel port. The parallel port provides the communication. The reason the board has a USB port is only to provide power to the board from the computer. If the USB connection is not plugged in to the board, the board will not have the power needed to function correctly.

  • How to output 0-10V to AVI+AVI-?

    In the motor outputs, the spindle should be set to pin number 3. This is also the output terminal number 3 (O3). In Mach3: Select [Config], select [Ports and Pins], and select [Spindle Setup] page in the popup dialog box. In the Motor Control box, check Use Spindle Motor Output and select PWM Control.

    [Use spindle motor output] is checked, Mach3 will automatically enable the spindle motor output pin. Click OK when the pop-up happens that will say "Spindle Motor has now been enabled. Ensure you set its pinouts.

    Next, select the Motor Outputs tab. At the line where [Signal] is [Spindle], check [Enable], modify [Step Port] to "3", modify [Step Pin#] to "3", and specify O3 as Is the output terminal of the PWM.

    Press [OK] button to save. Connect the indicator (refer to the previous section) to O3 for debugging. When the program "M3"executed is, O3 output signal can be seen.

    The AVI+ and AVI- corresponds to the ACM and AVI terminals.

    Additional Information:
    In the answer setting, 0-24V is output to out3, but not to AVI+/ACOM.
    Of course, 10V is given to the 10V terminal of the board.

  • how do you automatically turn on the router with pokeys57cnc and mach3. Mach3 is different from the mach4 example "step by step guide".

    There is a video on this page:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board
    that demonstrates the start and stop for a spindle with the Pokeys57CNC controller and Mach3. The video is titled, Spindle Start/Stop Control.

    If you are trying to start/stop a router rather than a spindle, all you need to do is apply the same concept of using the relay by passing the black (live) wire of the power cable through the relay. The Mach3 configuration is the same.

  • Backlash correction is not reflected in Mach3 Turn. Is there a way to reflect it?

    Mach3Turn has backlash settings under Config -> Backlash. You will be able to set backlash parameters in distance for each axis and/or by backlash speed percentage of Max. Make sure to enable the backlash compensation by clicking on the Backlash Enabled checkbox.

    It is highly recommended that you resolve any backlash in the mechanics of the machine rather than relying on the software to compensate for backlash.

  • You can set the Index input with Mach3 Turn and check that the Index is lit on the screen, but it is not reflected in the rotation speed. Is there any way?

    Yes, you will need a sensor to determine the speed of the rotation. For instance, you can use a hall effect sensor and put a magnet on the shaft of rotation. By installing the hall effect sensor near the shaft that contains the magnet, you can use this to determine the RPM of the axis and reflect this value in Mach3 using an input in your controller and setting that input in the index line item of the Mach3 input signals dialog box.

  • How do I wire two motors on the same axis?

    Yes, you can use 2 motors in the same axis output, however you will still need a driver for that stepper motor. Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

    The wiring scheme would look like this:
    The step and direction output terminals on the CNC controller interface for the axis you want to have two motors would connect to both drivers of the two stepper motors on that axis.

    Additional Information:
    I have been running two motors from the same driver for 10 years on my 3m x 1.6m router. Both motors driving the gantry are wired together. I see no reason to use two drivers. The motors are high torque Nema 34. I've had no issues.

  • The slaved axis moves slower that the other motor on the same axis

    If you have a slaved motor, you need to make sure that the two driver's dip switches are set the same so they both use the same microstepping.  You also want to make sure that one of them is not losing steps by setting the motor tuning in such a way that the motor torque has a sufficient buffer.

  • The tube is illuminated but I don't get clear firing to the piece. This is a rastering work and I get faint results and then it will be fine, then nothing. Tube changes from pink to solid line purple even when vectoring or manually holding the fire button.

    If your laser machine needs to reflect off of three mirrors before it finally passes the focal lens, then I would recommend realigning the laser.

    You might also want to see if the nozzle is hot. If so, then the laser energy is hitting some of the nozzle body and not all of the laser energy is exiting the small aperture of the nozzle. To determine if this is the cause, remove the nozzle and try the operation again to see if you have better results. If the results are better with the nozzle off, then realign the mirrors. If you are still having difficulty getting the laser energy to exit the nozzle, increase the diameter of the nozzle aperture.

    If you are still having poor results, take a look at the focal lens and the mirrors for any debris. An unclean lens and mirrors are a common cause of poor lasing performance.

  • my motor only goes one direction. I checked all the wiring and it's correct. Any suggestions?

    The video showing the hookup of the large motors showed a sequence that was not correct, or I totally misread what was recommended. I hooked the first motor up that way and it would only go in one direction in a very jerky mode. I confirmed that i had hooked it up the way the video showed, disconnected the wiring that runs through to the motor and reconnected it, thinking maybe a cold solder joint was the problem. No good. I finally went to the motor page that showed a different connection pattern. I tried the one that the motor page said to do, and it works smoothly and in the right direction now.

The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

  • Can you control the VFD from mach3?

    Yes, you can control the VFD using the a relay.  You will need to connect the relay output (NO) to the forward terminal of the VFD and the gnd terminal.  You will need to look at the diagram for your VFD to determine which gnd to use in the set of terminals that is associated with the forward terminal.  The forward terminal may be called something else, but the manual will tell you (something like X1, or D1, etc.)

    You will also need to change a parameter in the VFD to use the external terminals as opposed to the control from the control panel.

  • I purchased the Mach3 USB controller, however when I ran the test procedure, I get no response from the board, however the light comes on but does not flash when I Press the arrow keys, and measurements with the multimeter shows no voltage on the output connections. the meter shows 24 volts on the 24 volt connection across 24v and DCM. I believe the board is corrupt.

    Does the board's light come on at all? Did you try only connecting the controller to the USB, without the 24V connected to see if the board is functioning?

    Thanks

    Additional Information:
    Hi Patrick, Larry Here, I'm still having the same problem with the new board. When I plug the usb cable in the board, I get the flashing light but when I measure the voltage on the output pins I get no voltage at all. Mach3 says that the pins, 1 thru 4 are enabled and the output is enabled on all the pins just the way I set them, but no joy.

  • What is the minimum RPM for the 2.2kW spindle?

    Spindles with 2 poles, which is typically for these types of spindles will have a minimum RPM of 6000 RPM or 100Hz; however, I would not run the spindle below 15000 RPM or 250Hz to give a safety factor and no damage will occur.

    If you have a 4 pole spindle, then much lower RPMs can be achieved, and with higher torque than a 2 pole spindle. The 4 pole spindle will require more power than 2 pole spindles and will not be able to achieve as high maximum RPMs.

  • Is the housing grounded through the ground pin on the spindle connector

    The protective earth should be connected to the spindle housing in some way. Sometimes the 4th pin is already connected to the housing, but not always. It is always good to check by removing the 4 screws of the connector to confirm this. If it is not, you can use one of the connector screws as a way to connect the PE to the spindle housing. The screws of the connector has a direct connection to the housing of the spindle.

  • My stepper motors are randomly and frequently stalling while using the Pokeys57CNC controller board, any idea what could be the issue?

    I would suspect that the velocity and/or acceleration is too high for the amp setting on the driver. Consider increasing the current amp setting on the driver is the motor can handle the current, or decrease the velocity and/or acceleration.

    You might also want to check to see if you have any mechanical binding on the machine. To check, remove the mechanical drive mechanism so the axis slides freely and slide it from end to end to feel if you have any tight areas or binding.

  • the relay on the 57CNC card turns on and the VFD starts up but it won"t turn off. Relay #1 stays on all the time. Even the Estop won't turn it off. Relay #2 doesn't work all

    Turns out it was an electrical noise problem from the VFD. Troubleshooting showed me everything worked perfect even with the drive powered up but when the VFD started it would NOT stop from Mach3. I had run shielded cable and grounded it in the VFD but I had an intermediate break in the shield wire at my Master Control Relay (MCR) that is activated by an Estop on my control panel.

    This confirms the importance of shielded cable and making sure that the shield is contiguous.

    My guess is the wire(s) going to the dry contacts on the relay carried enough energy to fire the base of the transistor supplying coil voltage to relay #1. Or there might have just been enough induced voltage to the relay to fire the relay coil.
    I've fought similar VFD noise issues for 25 years and it still amazes me how pesky it can be. It's impossible to maintain any separation of signal and motor leads in the tiny space in the VFD.

    You want to make sure that the motors will be able to provide the necessary torque since there will not be mechanical advantage using roller chain. You will need a way to fix the chain to each end. I like to use #4 - 3/4" screws and #4 nuts. You will need a drive sprocket for each axis and a couple idler sprockets on each axis to serve as tensioners and guiding the roller chain.

    Yes, you can add a touch plate kit. A touch plate works just like a limit switch. All you need are alligator clips and a conductive plate. Solder a wire to the conductive plate material and connect that to an IN (input) terminal. Connect the alligator clip to the gnd of the input and then to the end mill. Enable the home setting for the Z axis in Mach3 or Mach4 and use the "ref all home" button to home all of the axes. The z axis will home at the touch plate. Make sure that the touch plate is under the end mill when the z-axis is in the homing process.

    Here is a tutorial I made a while ago that explains this:

  • I am using Windows 10 and my Shopbot PRT 4g uses Shopbot's proprietary software https://www.shopbottools.com/support/control-software. How can I determine if the 4th axis you offer will be compatible with my machine?

    Generally, you’ll need to check what control software will need to be used with the CNC router. Our machines use industry standard electronics and control software that is nonproprietary so you can use just about any software out there with our machines.

    Specifically, what software are you planning on using?

    Additional Information:
    dear Sir,
    I'm searching for the best one,I think that I have to learn more about that in order to be able to make the right decision.

    Additional Information:
    If you are using a computer running Microsoft Windows, then I would recommend using Mach3 or Mach4. If you prefer Linux, then LinuxCNC is the best control software in my opinion.

  • mach 3 pockets cuts are 0.5mm undersized always but outside cuts are prefectly accuracte, i have tried both parallel version and the 100 Khz rnr motion controller, i'm using DM542 as my motor controllers there are no errors in my codes or no mechanical errors

    This may be an issue of conventional vs climb cutting direction. I would recommend trying the opposite on your inside profiles and pockets and check. Let me know if this worked and what you are using for your inside cuts before the change.

  • Fabricator Pro 4x8 plans, electronics, hardware and mechanical components....is this a wood gantry machine? What all is not included?

    There really isn't any specific brand. We purchase the components in a disparate fashion from China. I will product a video today that shows all of the components that we use and also offer the components on the website.

    From the upcoming video, you will be able to identify the parts is you feel you want to search for these components yourself.

  • How do you configure usb cnc and the mk1 board to toggle the laser? I use jscut.org to create gcode files and am wondering if I create a setting to disable the laser when it goes a certain distance above 0 on Z+.

    I recommend using a an output terminal to turn on and off the laser for safety. All you need to use is the M7 (or 8) to turn the laser on and M9 to turn it off. These M codes are use in conjunction with the output terminals to control external devices. The last Pokeys57CNC tutorial part explains this concept. You can use this idea with your controller.

  • Does the anti-backlash nut require any maintenance or lubrication?

    If the anti-backlash nut exhibits a great amount of resistance, I typically add 3-in-1 oil to the lead screw and turn the lead screw so that the anti-backlash nut travels from end to end a few times. A drill comes in handy for this operation.

  • What is the best way to determine speeds and feeds for machine and bit longevity?

    The speeds and feeds are generally based on the amount of flutes that are being used per pass and how hot the end mill is getting when milling.  You want to use as much of the flutes as possible on single cuts.  Make the deepest cuts you can to increase the life of the tool.  For instance, if a tool that is 1 inch in cut length and the depth per pass is 1/4", then only that 1/4" is being used for the cutting.  The 1/4" tip of that tool will wear faster.  
    Make sure the feedrate is as fast as possible without a cost to the edge finish.  This will keep the end mill cool since there will be minimal friction as you are always cutting into fresh cooler material.  
    Use the end mill manufacturer's chip load for the tool to determine the starting feed rate.

    Feedrate (IPM - Inches/Min) = Spindle RPM x # of Flutes x Chip Load
    See each end mill for the chip load value.

    If your machine cannot achieve these feed rates, reduce the spindle RPM using this formula:
    Speed (RPM) = Feed Rate (IPM) / (# of Flutes x Chip Load)

  • limit switch does not work as wired mach3 usb

    Are you connecting the limit switch in normally open mode? I would suggest connecting a single limit switch from the DCM terminal to one of the input terminals. Make sure you have a 24v power supply connected between the 24V terminal and the DCM terminal.

  • I have a KL23H2100-30-4B motor with a KL-4030 driver and my motor stalls if I set the rapid above 180 imp.

    What mechanical drive system are you using? If your mechanical drive system connected to the stepper motor causes the motor to spin too fast, then you will be reaching the torque limit of the motor under the load of your axis.

  • stepper switch settings

    On the top of the stepper motor drivers is a grid with the appropriate toggle switch positions for the lead screw being used. If it is 2 turns per inch, the proper toggle switch positions would be 01101110. Try this and see if it works.

  • looking at woodsmith CNC and wanted better understand how it is wired. is it possible to get better wiring diagrams or manuals?

    There is a wiring diagram in the instructions on the following page:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    In the instructions, you will find the wiring diagram and further instructions below that with greater detail on how to connect the various features of the Mach3 USB controller that is used in the Woodsmith article.

    Note in the wiring diagram that COM- is the DCM terminal and COM+ is the 24V terminal.

    Additional Information:
    I built one of those and complained to Woodsmith about the wiring diagram. They said the vendor changed boards after the article went to press. Don't trust anything in their diagram. They even got the power supply wired wrong. I had to view the instructions from buildyourcnc to get things working. You will fry you drivers if you do anything that is referenced in the woodsmith article. While I did get it built and working, I had to make modifications on many of the dimensions to get it put together right. They make no mention of the tight tolerances required or how square and level everything must be. The beast works but the publication leaves you dangling when it comes to the important details after you get it built.

  • On Mach3 USB the port number is 3 but i dont see the motor output pin numbers for the stepper side? could you please provide this for me? maybe a sketch of all the pin numbers the way Mach 3 sees them?

    The step and direction terminals on the Mach3 USB controller are the terminals labeled XP, XD, YP, YD, ZP, ZD, AP and AD. The P is the pulse or step terminal and the D is the direction terminal.

    The configuration for the motor outputs are already configured in the Mach3 configuration file that is available on that product page:

  • I purchased the large gantry system with USB control. I have built the CNC and it is working fine. Now fine tuning the motors. On the X-axis I have the Velocity set at 60 (inches), Acceleration at 1.4, the Step Pulse 1-5us and Dir Pulse set at 0. Do I need to adjust the pulses?

    The steps per unit is automatically determined in the calibration of the axis by clicking on the "set steps per unit" button above the reset button on the settings tab. Initially set the velocity and acceleration to a low setting, like 100 and 10 respectively, so that the axis does not stall during this operation. Once calibrated, the steps per unit will be set to the correct value and the velocity and acceleration can be increased. I have a video explaning the tuning of the motors on this page:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

    The name of the video is Test and Tune the motors.
