  • How fast can I cut 1/4" wood with the 40 watt CO2 laser?

    CO2 laser will not cut wood material fast at all. This is just the nature of the laser energy. The wood is a very low absorbent of the laser energy and you will need to run probably around 10 ipm to cut through the wood. CNC is much more efficient for cutting and laser as more efficient at marking or slowly cutting if you need the small kerf. You will also need a relatively high output air source to cut efficiently. The air will blow away the char (carbon) on the wood. The black char will absorb most of the laser energy not allowing the wood to be cut well. We use a compressor for the air source, but you can use a commercial hydroponic air pump instead.

  • The motherboard on the computer I bought from you went out. What would you suggest. I have a laptop, could I use it and use a Mach3 USB interface board?

    Yes, you can use a laptop if you have a controller that uses a USB, like the Mach3 USB card. If you don't have that, you can purchase that part here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    If you have a controller board that connects to a 25 pin connector, modern laptops will not be able to connect to that port.

    How old is your CNC computer system?

    Additional Information:
    The CNC computer system is 2013 (5 years). The built in video card went out. I will order the Mach3 USB card. Thank you.

  • I recently purchesed a USB Mach3 breakout board and need help setting mach3 to use a relay to start the router can you show how to set the pins and which port to use on the board to attached the relay?

    Sure, connect O2 (output #2) on your mach3 USB board to the GND side of your relay coil. Connect the 24V power supply to the positive side of your 24v relay.

    You will want to connect a flyback diode (1N4007) between the coil connections to make sure the coil back current does not damage the Mach3 USB board.

    Refer to this diagram:

  • I was wondering what you recommend to use to cool your spindle when continuously exposed to freezing temperature. Can I use winter windshield cleaner (cheap) or do I have to use antifreeze engine coolant or something else? water just sounds like a really bad idea. I live in Canada Eh!

    Using Anti-Freeze in the cooling system with either our spindle or our laser tubes will not have any problems and we recommend using a small amount in locations where temperature is freezing or below.
    Although we do not recommend using an entire gallon of anti-freeze rather just a small quantity with tap water will be sufficient.

    Additional Information:


    Additional Information:
    All last winter, the temperature was below freezing and sometimes below zero. I used 100% antifreeze for the spindle coolant. Worked great !! All the spindle needs is any type of coolant flowing through it to take the heat away. I use three gallons of antifreeze in a tub with a fish-tank pump to push the antifreeze through. 100% antifreeze works great in cold or hot winter.

    Additional Information:
    Excellent tip. Thank you for this correction. So it is OK to use antifreeze solely as a cooling method.

  • I ordered an 80w tune on Amazon for a good deal, it took over a month to arrive and was broken on arrival. Get what you pay for I guess :( of I order a tune from you can I expect it to be better packed and arrive quicker?

    We double box our tubes. The inside box contains the tube that is surrounded by foam. This inner box is wrapped with bubble wrap and then boxed again.

    Carriers are not very careful with packages, but it is not typically from personnel handling, but the machines and conveyors that maneuver the boxes at their distribution centers.

    Additional Information:
    Here is more elaboration from PoLabs and a question regarding the need for multiple devices:
    Although the PoKeys plugin for Mach3 supports multiple PoKeys devices, only one device can be a motion controller. Since, PoKeys57CNC is always configured as motion controller by the plugin, there shouldn't be more than 1 PoKeys57CNC used by the plugin at a time.
    May I ask you about the application and why there is a need for multiple PoKeys57CNC devices?

  • 4 axis kit can I use 2 motors for the gantry with one controller card? or I buy the 3 axis kit instead?

    Yes, you can use the 4 axis kit and use two of the motors on the gantry. You will need to wire the gantry axis motors to the same step and direction signals on the controller interface. For example, if the gantry axis is the X axis, then on the controller step and direction terminals (CP and CW) is wired to both of the stepper motor drivers for the X axis.

  • I can turn the flood coolant on using the toogle in Mach3 so Mach3 is talking to the PokeysCNC board (using output3). In spindle setup, Output3 is assigned to flood and the disable box is not checked. Output 3 is enabled and assigned to the correct relay. However, coolant does not come on when the spindle is turned on. Any suggestions about what I am doing wrong would be appreciated.

    You may need to add the m7 or m8 code to turn on the coolant or mist and m9 to turn it off. I will look further into this to see if mach3 can turn on the coolant when the spindle is turned off. I believe the coolant is a separate function from the spindle control since you may not need coolant for every material that you will be milling.

    Additional Information:


    Additional Information:
    I have tried typing M7 and M8 into the MDI with no success. I can toggle the coolant on and off using the flood control button. Water flows and the LED lights on the diagnostic page. I followed the setup instructions in the video on the Pokeys57CNC page, which includes the spindle setup page. Those videos are very helpful.

    Additional Information:
    To close this question - The M7 M8 commands did start working. I never figured out why they would not work before. I still cannot get the coolant to turn on with the spindle from the Mach3 set up. I have given up and just make sure the M command is in the g code.

  • My pokeysCNC board creates and analog signal of 0-10V for 0 to 24000 spindle rpm just like it should from Mach3. However, when the spindle is on, the voltage only gets to about 3.8V for 24000 rpm. It seems like the vfd is drawing more current than the pokeyscnc analog output can produce. It there an easy solution to this problem?

    Do you have the Pokeys57CNC connected to a 24V external power supply?

    Additional Information:
    Yes, a 24V external power supply with the jumper positioned. I'm using the ethernet port so the 24v is the only source of power. I plan to measure the amp draw when I have a chance to see how much the vfd is drawing on the analog out.

    Additional Information:
    Further information. The resistance across the terminals on the vfd is 22k ohms. With an independent 0-10v current source I can run the spindle from 20 to 400 Hz. The PokeysCNC only gets to 3.8v with the vfd attached (and the vfd is at 150 Hz) compared to 10v when the vfd is not attached. The power to the PokeysCNC is steady at 24.18 V, so I'm not maxing out the power supply. Still looking for thoughts on what might be going on?

    Additional Information:
    And the other thing - The measured amperage is 0.17 mA for the 0-10 V signal (which makes perfect sense for 3.7 V and 22k Ohms).

    Additional Information:
    Just to bring finality to this issue - I added a 2.2 microfarad capacitor across the 0-10V input terminal (from signal to ground). This solved the issue. Evidently, it was an electrical noise issue.

  • reverse stepper motor direction on pokeys

    When trying to use two motors on a single axis, there is a multitude of methods to get them to work together.
    First: There should always be a slave option in the CNC control software(mach 3/ planet-cnc/emc2/etc.), this will be the easiest way to make the dual motor configuration work. However some adjusting might be necessary due to the orientation of the motor when mounting it on the opposite side of the CNC machine.(Mach3/config/slaveaxis, planet-cnc/file/settings/axes).

    Secondly: Dealing with our interface boards(maybe third-party as well), you can have two drivers going to the same axis on the interface board. Which then will have one motor per driver, this will use the same motion and control from the (ex.) x-axis to driver two motors. However some adjusting might be necessary due to the orientation of the motor when mounting it on the opposite side of the CNC machine.

    Adjusting of the driver or motor wires, can be done separate from the control software with the use of a hex inverter, that can be used and to switch the signal (ex. takes a low signal and brings it high, and takes a high signal and brings it low) of one of the motors, to run the same as the other motor.
    There is also another method of inverting the orientation of the motors movement without the use of a hex inverter. This method you will have to wire the coil's of the motors oppositely of what is recommended for one of the motors. Example, you will wire our Nema 24 as follows(recommended): A+ - red/blue, A- - yellow/black, B+ - white/brown, B- - green/orange. However to run another motor with with it you will have to switch the A/B connections to: A+ - white/brown, A- - green/orange, B+ - red/blue, B- - yellow/black.

    These method's are usually needed/used when trying to control two motors and setting it up without the help of the CNC control software, and also due to the mounting orientation of the second motor, the inverting the direction of motion will be necessary so they work together instead of working against each other.

    Mach3 and Mach4 typically use specific controller cards that are compatible with the software.

  • How do I put 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.

  • Can I buy an asembled gauntry for the 4x8 table heavy duty only and pick up?

    Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)
    To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").
    The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.
    Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.

  • how to calibrate stepper motors with ballscrews In mach3

    The easy way is to use Mach3's calibration process to calibrate the axis with the ballscrew coupled to the stepper motor. This is done in the settings tab of Mach3 and clicking the button just above the "Reset" button called "Set Steps Per Unit". A dialog box will appear asking how far you want Mach3 to move that axis. Mach3 will move that axis at a distance that is determined by the existing steps per unit value set in the motor tuning dialog box (config menu -> motor tuning). Not knowing the distance that this axis will travel, it's best to use a very small value.

    The more difficult way and the technique that should be used to create the initial value for the step per unit in the motor tuning dialog box. Use the steps/unit formula. This example will use inches.

    Steps/Inch
    = ((motor natural steps) x microsteps) / (the travel for one complete revolution)

    The travel for one revolution would be the distance a ball nut will travel with one complete turn of the ball screw. This is generally the number of starts / threads per inch. Say the ball screw has 5 starts (5 threads starting from the beginning of the screw) and 10 threads per inch (TPI), then the travel for one complete turn of the screw would be 5/10, or 1/2".

    Say you set the microstepping to be 1/4 on the stepper motor driver and your stepper motor has 200 natural steps per revolution (1.8 degrees per step), then the total steps would be 200 x 4 = 800.

    So, the steps/inch is 800 / 1/2" = 1600 steps per inch

    Hope that helps

    Do you have anything connected to the relay?

    Additional Information:

    Additional Information:
    Nothing is attached to the relay pins I am only using 2 and 3 and 5v for x driver and led indicator, 4 and 5 and 5v for y driver and led indicator, and 6 to fire the laser and the led indicator. I am also using a 5v out for the laser power control circuit and one pin of the 5k pot. Ground is shared on the laser power supply, the cnc power supply and the x and y driver. I am using the computer motherboard supplied by Buildyoucnc running ubuntu 12.04.5 LTS and linuxcnc. Bios is set to use ECP, I have tried normal and I have tried EPP, all with the same results. If I plug in the parallel after the computer starts up it doesn't switch but I can't control either axis motors


    Additional Information:
    Laser is currently not connected for safety reasons


    Additional Information:
    I am using the parallel BoB for the 40 watt C02 Laser Cutter and Engraver(blacktooth), with the supplied integrated computer running Ubuntu 12.04.5 LTS and linuxcnc. Right now, when I have the parallel header connected to the BoB(as well as usb power supplied by the computer) and I start the computer, I am able to see the first splash screen of text indicating that the computer is starting up, then the relay on the BoB switches, turning the computer off and then back on again. This happens over and over again and the computer cannot fully start into the linux os. If I unplug the parallel cable from the BoB, I can start the computer, sign in and then plug the BoB back in without it shutting down the computer. Can anyone explain why this happens? I should also say that I cannot talk to the steppers in stepconfig of linuxcnc, I get to the test this motor section and nothing happens when I try to jog either the x or y motors. In the y config, I actually triggered the relay and sent the machine back into the start up failure loop I mentioned in the beginning.

    Additional Information:
    Fixed this problem, the parallel cable was not seated well, found some screws to make a strong connection, now that part is working. Unfortunately, the stepconfig in linuxcnc is still not talking to the motor drivers and the setup for determining steps for inch in the build instructions is nothing like the set up in linuxcnc. In the instructions it says motor steps per revolution*microsteps/pulley pitch per tooth*number of teeth and in this case the recommended input would be (200*16)/.08*20 teeth = 2000 steps per inch the formula in linuxcnc is very different

  • How should I wire the E-stop button? NC or NO?

    I would recommend wiring the E-Stop to an input terminal via an NC connection. This is the industry standard. It requires a NC (Normally connected) circuit for the machine to be operational, and when the circuit breaks, the machine shuts off. This is better than having a circuit NO (normally open), open circuit that requires a circuit to be created to have the machine shut off for safety.

    Hey - the model number on the laser controller is
    AWC708C
    S/N:708014243

    Additional Information:
    Do you need any additional information here? I really want to get going on it this weekend!

    Additional Information:
    Sorry about that. If you are referring to the CN1 and CN2 connector, I don't believe it is needed if it didn't come with the connector. The components that we send to the customer is the same package that is sent from the manufacturer of the product. I would try connecting it to the CN1 connector of both units and test the interface (control panel).

    Additional Information:
    The manual for the AWC 708 shows the two ports CN1 and CN2 connected, but that may just be for thorough documentation if the CN2 is needed for some reason. Do you have a copy of the manual or know where to find it? If not, I will put the document link here.

  • When I try to run Mach3 It just crashes and restarts my computer.

    What Windows version are you running? I have heard of a windows update that crashes Mach3. Try uninstalling Mach3 then re-installing it to see if that works. Make sure to save your .xml files under the Mach3 folder or you will lose your settings. Also, copy your license file under that folder so you can re-copy it into the new folder.

    Another solution is to roll back the windows update to a previous version (just prior to the update).

  • How should I control a plasma torch, spindle and a laser on my CNC machine?

    It will depend on how you configure the machine to use the Laser and plasma. Is the laser on a separate gantry? That will determine the way you will connect the laser control system or if you use a typical CNC controller. The plasma will need inputs of THC on, THC up, THC down and outputs to trigger the plasma torch. I recommend the Pokeys57CNC for the plasma and you can also fire the laser with it, but you will not be able to do engraving with the laser unless you use a laser controller. If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using, or if you have the laser on a separate gantry, you can use a traditional laser controller connected to the stepper motor drivers on that gantry.

    Users response:
    I was planing on using same gantry, and installing plasma and laser module on z axis along the side with current router. Perhaps if it’s needed installing another z axis on current z axis. So that when I use plasma, router z will be homed and plasma z axis will be able to utilize thc.

    When you say “If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using,”
    If i install laser controller, pokeys and router motion card, do you mean all ( axis and router/laser/plasma) signals or just the one that controls router/laser/plasma?
    I was wondering if I could jump (parallel connect) axis signals from card to card without ?
    Also do you prefer ethernet card or usb?
    I really do appreciate your help :) thanx again.

    Buildyourcnc response:
    Not a problem at all.

    Remember that with all of that weight on the z-axis, you will not be able to do efficient raster style engraving.

    By putting the laser on another gantry, say at the far end of the table, then you would be able to use a laser controller that controls its own stepper motors and the nozzle can have fast swing motion for engraving. With the laser on the z-axis of the spindle (like see on the greenBull), you will only be able to do vector motions for the laser.

    You can also have a CNC interface and laser controller controlling the same stepper motor drivers, but you will need a few tri-state buffer chips where you can use a toggle switch for which controller has control of the drivers.

  • Looking for electronics for a plasmacam table. It's going to to be a 5'x10' table with x,y,z axis. Will be running on windows ten with a hypertherm powermax45 xp plasma cutter. Any information or links would be greatly appreciated!

    What electronics do you have at the moment? Depending on your machine, you will need a minimum of 3 stepper motors and 3 drivers (unless your heavy axis requires two stepper motors and two drivers). You will also need an interface board that is capable of providing three inputs for the THC (Torch Height Controller), THC on, THC up and THC down, and outputs for firing the torch. I would recommend the Pokeys57CNC interface for the primary interface. This interface will connect to the stepper motor drivers and the THC. The Pokeys57CNC can also communicate via USB or Ethernet.

  • Can I use the driver's I have with the Pokey57

    Since the Pokey57CNC outputs standard pulse and direction signals, you can use any stepper driver. So, you do not need to use the Postep driver to operate your stepper motors.

  • My computer doesn't have a parallel port connection. Can I use a usb to parallel port cable to communicate with my breakout board?

    A parallel to USB adapter will not work. You will need to use a USB interface like the ones below:

    Mach3 USB interface:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    Poeys57CNC Interface:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

    Additional Information:
    To answer the question in more detail, the parallel port is actually an extension straight from the CPU and is also called the GPIO (General Purpose I/O) pins. These pins carry signals independently, hence the description as being a parallel port.

    The stepper motor driver receives a pulse train (series of pulses). A single pin on the parallel port sends a pulse train to one stepper motor driver and stepper motor for a single axis. Another pin on the parallel port sends a pulse train to another stepper motor driver on another axis. This happens simultaneously as with the direction signals for each axis.

    If a parallel port is adapted through a USB (using an adapter), the parallel port cannot have these signals happen in a simultaneous fashion and will cause the stepper motors of a CNC router or machine to be very clunky, if it works at all. To elaborate, the computer sends an instruction to the USB to send a high signal to pin 1, so it does, then another signal to pin 2, so it does. This is happening one after another. The speed at which this happens is reduced dramatically, and the position of one axis may now be out of sync to another axis.

    The reason the USB interfaces (linked above) work is that the USB delivers broad instructions to the interface (to a microcontroller) and the interface parses the instructions and outputs simultaneous signals to the stepper motor drivers.

    Hope this helps.

  • I forget the term for it, but are the encoders "absolute" in regards to their positioning? So if for some reason a cut is interrupted the machine can regain its position?

    Feedback and positioning:

    - Open-loop is where the computer does not have feedback, but it has the current position as per the number of pulses it has sent to the stepper motors. As long as the stepper motors are tuned so that there is a safety factor, then your machine will always be at the correct position. This scenario is common and typical for CNC machines

    - Closed-loop is where the computer receives feedback from the motors and is common on very high end CNC machines. The computer sends the pulses, or signal for the motors to attempt to achieve a particular position. The servo motors will use a PID (Proportional Integral Derivative) to continue to achieve a particular position where the driver/computer will tell the motor to go back and forth (getting better as it goes) for the position. This back and forth (the PID in action) is usually imperceptible.

    The blackTooth is a laser cutter/engraver, and its current design directs the beam in 2 dimensions (X and Y) over the surface of a workpiece which is assumed to be lying flat beneath the laser head. There is no mechanism to move the Z-axis directly. There is likewise no direct provision to move either the workpiece or the laser head for a 4th or 5th axis of operation because that would change the optical path and/or the focal point. However, you could certainly add a 4th axis to move a workpiece beneath the laser head -- it would be an interesting project, and if you do it we would like to see pictures.

    The ability of the software to support this addition depends upon which software you are using. If you are using a breakout board and machine control software designed for conventional CNC mills, such as Mach3, LinuxCNC, or PlanetCNC, then the answer is yes, the software will support the 4th axis quite easily. If you are using the integrated laser controller, the adaptation would be more difficult.

  • Hi Patrick right now I have a parallel port cnc machine that I built in 2013. I want to update my system to use a usb. Do you recommend changing my interface board to a Mach3 USB interface board or purchasing the UC 100 parallel port to USB adapter?

    Do you have any intention to upgrade to Mach4? If you will be staying with Mach3 for a while, then the Mach3 USB interface is fine. If you intend to change to Mach4, then I would go with the Pokeys57CNC interface.

  • we just received two nema 11 stepper motors per our order--USR2-2, however they are single shaft, we need double shaft, I thought that's what we ordered. We're sending them back, let me know if you do have the double shaft version and I'll try again to order them. I notice the model number on the motor ends in "A", where the packing slip shows "B".

    We just received our new inventory of motors and that specific stepper motor ski came back with only one shaft. I’m not at the office to look at this inventory, so if that is true, they will all be single shaft. We may have other stepper motors with included rear shafts, but I will have to see on Monday.

    If I don’t have the double shaft, we will provide a refund upon receipt of the motors. My apologies for this error.

    Additional Information:
    Hi, I'm sending these motors back today. As I understand you, you might have some motors from the previous lot still in stock, and these would be double shaft but otherwise you don't have any and won't be getting any. If you do have two double shaft versions of this motor please send them; if you don't have two of them please let me know--today if possible--so I can start looking elsewhere. Thanks, Ted Armen

  • Will the Mach3 interface board accommodate 5 wire steppers?

    Wow, I've never heard of 5 wire stepper motors. Typically, stepper motors have two wires per coil (the start and end of the coil) and sometimes there is a midpoint wire on each coil making for 6 wires. Other stepper motors may have the midpoint cut and two wires extending from the midpoint (essentially making 4 coils) which creates 8 wire stepper motors.

    Having 5 wires seems odd to me. Can you measure the resistance between the 5 wires with all combinations?

  • When we simulate cutting a part, the part is 40% larger than it should be. Why?

    What software are you using to simulate the CAM machining operations?

    Additional Information:
    I drew my part in ViaCad, opened part in CamBam to produce GCode, then Mach3 to simulate cutting part. Everything worked as it should but part was too large.

    Additional Information:
    It sounds like steps per unit is not calibrated properly. Use the Mach3 to calibrate the axes. In the settings tab, there will be axis calibration labeled just above the reset button. There is a button just just below axis calibration called set steps per unit. When the button is clicked, mach3 will present you with a dialog box asking for a measurement of how far to move the specific axis you need to calibrate (use a number that will not make the machine over run the axis). The machine will move to a certain length. Measure that length and enter it into the next dialog box that Mach3 presents to you. Do this for each axis.

  • Which controller(DSP or FPGA or other) is best for CNC machine for G code interpreter operations?

    It's probably better to use an FPGA or a microcontroller that is clocked (provided by a crystal oscillator) fast enough to simultaneously output pulse trains for the number of axes you intent to drive on the CNC and to provide for other processor operations, like spindle control, processing inputs from the machine and other outputs you may have (mist, coolant, etc.).

    Additional Information:
    Hi,

  • I would like to build a low cost laser engraver/ cutter, can your 40w laser power supply be controlled with an arduino or is it only controlled by the controller sold here?

    You can control our 40W laser power supply (which controls the laser tube) with an Arduino, if that is your intention. The trigger for turning the laser on and off uses a 5V level. To control intensity, you can use the Arduino PWM output. If you want the Arduino to move the machine as well (providing pulse trains to each of the stepper motor drivers) then you will need to make sure you consider the processing speed of the Arduino so you will be able to run the stepper motors at the speed you need for the laser engraving/cutting.

    Our laser controller do all of these functions. Here is a link to our laser control system:

    Additional Information:
    Thank you! I am building a 3 axis cnc/ engraver and I think this would be a good option as well as the router head and the 3d printing head. How heavy is the tube? I may mount it directly onto one of the axis of the machine to eliminate the need to line up all three axis, similar to what you have with your xl engraver.

    Additional Information:
    The tube isn't that heavy, but when filled with water, it can get up to a few pounds. The key is to use the axis moving the nozzle for engraving as this requires fast back and forth motion. The cutting is generally dependent on the axes moving from vector to vector at a relatively slow motion, so this is not a problem.

  • How do I calibrate my machine with mach3

    In Mach3, go to the Settings Tab, and select "Set Steps Per Unit". It will ask you how far to move the machine. Before you do this, make a mark on the table exactly where the end mill is resting. You can do this by lowering the end mill until it touches the material, then spinning it by hand to cut a small dimple in the material. Then, raise the end mill to clear the material, and assign a distance to move the machine. Once the machine moves and stops, measure the exact distance that it actually traveled with a tape measure, and enter this value into the dialog box that asks how far it moved. Mach3 will automatically adjust your steps per unit for that axis to be more accurate. Do this for all axes often to ensure you are cutting accurately. The longer distances you use calibrate, and the more precise you are with your measurements, the better.

  • x and y on plasma does not work but x and y on mill does work. why?

    I assume you are referring to Mach3 mill versus mach3 plasma. These are two xml files that contain settings for "mill" and "plasma".

    If the machine moves (the stepper motors are moving and the drivers are receiving signals from the controller) in the settings for mill, but are not moving in the plasma settings, then you need to deeply investigate the settings and make sure they are exactly the same in the:
    - motor outputs tab of ports and pins dialog box
    - port address in the ports and pins dialog box

    If you are just trying to move it manually, make sure the jog button is "on" in the program run tab. Press the tab button to reveal the mach3 pendant screen and make sure the jog is set to continuous.

  • wire size to connect Frequency converter to 2.2 KW Router?

    We use 16 AWG (American Wire Gauge) to connect the 2.2kW Spindle to the VFD (Variable Frequency Drive also called the inverter. Since there are three coils, the 2.2kW (2200 watt) spindle will draw 10 amps total or 3.33 amps per coil. 16 AWG will be more than enough capacity to handle 3.33 amps.

  • What wiring should I use to connect two motors for one axis?

    Yes, you can use 2 motors in the same axis output, however you will still need a driver for that 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.

    Also you can run a slave motor using another axis on the board, and setting it up in the Planet-CNC settings.

    Planet-CNC/File/Settings/Axes, here you will enter 3 in the Number of Axes location, and then change the Function of the Axis 4 to Slave 1. There you will have the 4th axis or A-axis be a slave for the x-axis.
