  • Whereb can I find directions on how to install the Mach3 USB board with Mach 4 software? I do not have a parallell port.

    You can find instructions for the Mach3 USB here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    You will probably need to use the Mach3 USB board with Mach3. We have not tested the Mach3 usb card with Mach4.

  • Patrick, I am having issues with the x axis on the vlxl..very rough movement. What should I adjust? Check the rail spacing or can I modify anything in the software?

    Sounds like a wire may have worked itself loose. Did this just start happening? If so, check for loose terminals with the motor wiring. Did you solder the motor wires to the extended wires that lead to the driver? If not, I strongly suggest these wires be soldered and a heat shrink tubing cover the soldered connection to eliminate the possibility of shorting.

    Additional Information:
    I am just now starting to work with the machine. Was on vacation. It has never moved smoothly on the X. Was hoping to get some phone time with you or Juan tomorrow. All the connections are solid as far as I can tell. Nothing is interfering. I'm wondering if the rail spacing is off. It moves fine when I manually move it.

    Additional Information:
    If it moves smoothly when manually moving it, but the stepper motor runs rough, then it is definitely a motor wire connection. Also, check to make sure the driver is set to 1/16 microstepping and the motor amps is around 5.

    Additional Information:
    What gauge wire did you use for the motor to driver connection?

    Additional Information:
    It was the black wire that was included. Pretty sure it's 18. I was worried it couldn't take it. Some of the 18 I have seen is only rated for 2A. I can rewire with that 4-lead cable you included If you think I should. The connections seem solid so that might make sense.

    Additional Information:
    18 gauge is more than sufficient for this stepper motor wiring. We use 20 gauge stranded wires in the 4 conductor motor cable.

    Additional Information:
    Sometimes wires can get chaffed, or there is a conductivity issue in some wires.I'm wondering if it would be goo to do a test rewiring the motor to the driver, but not putting it into the cable carrier, just to make sure that is the problem.

    Additional Information:
    What do you suggest I do? Just go over the wiring? The 18 is fine for 5.5A? All the switches look right. Set at 1/16. What are the natural steps on this motor?

    Additional Information:
    I’ll check the conductivity on the wires. I can just re-run it with that four conductor. That cable works fine for you guys?

    Additional Information:
    The 4 conductor cable is the only cable we use for these stepper motors. It's a special cable used for motion applications.

    Here is a link to that cable that we sell just to confirm the cable we are discussing:
    https://www.buildyourcnc.com/item/electronicsAndMotors-cable-wire-20awg-wrcon


    Additional Information:
    Yeah, that’s it. However, I ran the stock File on the laser cutter, the duck, it seems to run fine it’s just when you make the small adjustments with the arrow keys that it’s so rough. The other problem is that the speed on the stock file is way too fast.

    Additional Information:
    Ah, the jogging speed. I did not consider this. You definitely need to reduce the speed when you press the arrow keys.

    The speed when running a job (the file) can be modified in LaserCad.

    Additional Information:
    So, I’ll look into that. Everything is done besides for Putting the tube on and adjusting the mirrors. When are you guys available for a quick phone call?

    Additional Information:
    In LaserCAD, go to the options -> system options -> User parameters. Make sure to click the read button to bring the parameters from the laser controller to the software. Our Key_Move_Speed is 100 and our X/Y_Home_Speed is also 100. I wouldn't go any faster than that. Curious, what are your values for these parameters?

    Additional Information:
    Key speed was set to 200 and XY was at 50. On the duck file on the machine, it says the speed is at 200. How can I import that file to change it?

    Additional Information:
    Much smoother after that change. File is still too fast, though.

    Additional Information:
    In the file, the speed is built into the geometry. You will need to open the file in LaserCAD, select the geometry and modify the speed. Make sure to change the intensity as well to compensate.

  • I have your Nema 24 electronics kit and am having problems with the Z axis dropping over time. I am using a PC 8902 motor. Any ideas on what the problem is? What should be the motor tuning values in Mach3? Thanks

    Make sure all your bolts/screws are tighten correctly and if using a lead screw make sure your anti-backlash nut is not offset. Now a default setting will be 10101100 for your driver dip switch settings and in motor tuning (mach3) 1600 steps per, 400.02 velocity, 4 in acceleration. now the acceleration and velocity can be adjusted to move your machine faster, but if set to high they could stall. Make sure you have the correct wiring from your motor to your driver (https://www.buildyourcnc.com/Documents/PN.SM60HT86-2008BF-U%20(inhouse%20PN.60BYGH303-13)%20(1).pdf).

  • I had to wipe my computer due to virus and now can not download the USB software again. I get a "unhandled exception" error message. Any suggestions?

    An unhandled exception generally means that, in the program code, the program is not checking against every possible exception that could occur. Most likely, this exception is caused by some limit that is being exceeded (or the other way around). I would remove any files that could be associated with the program, like setting files, or even register configurations associated with that software. Also, make sure that you completely update your version of windows.

    Check to make sure all of the drivers are current for your graphics hardware. Make sure that your graphics hardware works in other programs as well.

    If you upgraded the Windows version, check to make sure your graphics hardware is compatible with the new version of Windows. Unhandled exception issue may be associated with graphics hardware and compatibility.

    Customer Response:
    I've given up on the wiped laptop and loaded the program on a different computer using windows 8. At first it won't operate my CNC until I read on Planet-CNC forum about loading the drivers on windows 8. All working now. Will run through the calibrations again today. Thanks

  • I'm new to CNC and just finish building my router.I need software for my post processor and not sure if your product is what I need?

    You will need a CNC software that will control your router cnc machine, and your design CAD/CAM software will need to know the CNC software you plan on using so the post processor in the CAM software can create the g-code for the CNC control software. So if you have for example, Mach 3 and our parallel breakout board, you can use the Mach 3 post processor in your design software.

  • If I build a Laser with the components on this site, can I cut the 0.1mm and 0.2mm board? Is it cut in optimal conditions, or if not what you recommend ?!

    What material is the 0.1mm and 0.2mm board?

    Additional Information:
    Steel sheet


    Additional Information:
    Steel Sheet

    Additional Information:
    Thanks for the response. CO2 lasers unfortunately cannot cut metallic materials. Metals are best cut with other types of lasers, or by using oxygen assist. The oxygen assist method is not encourages as the combination or CO2 laser and oxygen is very volatile.

    Additional Information:
    and I can not do this laser to cut the steel plate, but instead of the CO2 tube I put the oxygen tube, or do not I know ?! Do I have a chance in the products on the site to create a laser for 0.1mm and 0.2mm steel sheets?

  • I bought Nema 24 motors and driver package with usb board. What do i need to have more speed? Cant even jog past 25 ipm without the motor stalling (not having enough torgue)

    We recommend checking the dip switch settings on your drivers, having the correct microstepping/amp settings along with the steps/unit will help the motors run as effective as possible.
    This is a default parameter that we use while we test our motors:
    Driver dip switch settings will be at a 1/16 microstepping and 2.7amp (11001100) for x/y-axis and the z-axis will be at 1/4 microstepping and 2.7amp (10101100).

    In planet-cnc with increasing the motor speed, you will have to modify the settings in planet-cnc (File/settings/setup) you will modify the initial speed, maximum speed, and the acceleration.
    X/Y-axis step/unit: 1422.22 initial speed:500 maximum speed:750 acceleration:25
    Z-axis step/unit: 1600 initial speed:100 maximum speed:300 acceleration:25
    The initial speed and maximum speed will have to be roughly tested and adjusted per application.
    Make sure to adjust the JOG slide bard underneath the axis controls on screen to about 750, to compensate for your x/y-axis adjustments. If left alone the speed will max out at the default setting.

    Here is a video tutorial to calculate the steps required depending on your mechanical linear motion components. (

  • Hi I have a Proxxon MF70, I want to add 3axis stepper with controller and software by USB. Can you suggest a kit for me? Thanks.

    To implement a electronics combo to run you Proxxon MF70, you will need to find the correct drive components (ACME screw, linear rail, etc) and look into any specific modifications needed to your rig.
    I would recommend the USB 3 Axis Large Motors Electronics w/ USB Interface Board.
    Since the machine is metal, our larger motors would be highly recommended.

    We have not done this conversion, through research is recommended.

  • Do the 5 Axis Breakout Board with Relay requires software to setup

    The breakout board does not require software to run, specifically. The breakout board serves only as a signal conditioner where the input signal from the computer is output at the corresponding terminal, or the terminal receives a signal and is conditioned and sent to the parallel connector to be read by the computer. As long as the software can communicate to the parallel port of the computer, then the breakout board will function.

  • I have a MK1 board that I just got running and I am having issues. Do you have an MK1 board at your shop that I can send you my G-Code to run? The freexing/zeroing in the middle of the program issue happens even with no step drives attached to the board.

    My apologies for not getting back to you. We always answer the phones during business hours, so I would try that first. Our emails on Monday generally is stacked up as we are closed during the weekend. We can try your g-code here. Please send the g-code to the techsupport@buildyourcnc.com email address and we will test the code to see if it works.

    By the way, do you get movement on the planet-cnc UI screen?

    Additional Information:
    The program starts and runs normal. I have all the correct movement on the mill and the UI screen. Then one of two things happens. It either stops and resets all axis to zero in the middle of the part or it freezes in the middle of the part. When it freezes, it is not moving on the cnc or the UI screen. Sometimes after a freeze it will come up with an 'IO timeout error', but the only way to clear is to unplug USB and start over.
    I will send my settings and g-code files over tonight. Please be sure to load my settings when running the g-code. No movement of the cnc is necessary as the controller will do these issues without power to any drives and just the USB board connected, on my board at least.

  • [575] Everything works in mill, but if I wanna use turn software then there is problems to recognize rnrmotion card.

    Have you tried comparing all of the parameters for the motor outputs? For instance, go into the motor outputs screen in the mill profile, take note of all the parameters. Then open the turn profile, go into the motor outputs and change the parameters from the notes you had in the mill profile.

    If that works, do the same for the other setting screens.

  • How do I get Homing on Z to work with Plate and Ground using Buildyourcnc usb board all the entries for the sensor in planet-cnc are grayed out. I am using input z- and I purchased the software

    To home the z-axis using a plate:
    - Connect the end mill using a large clamping device like an alligator clip with a wire connected to GND.

    - Connect the plate (solder a wire to the plate) to one of the input pins.

    - You can use the autoset to setup that pin in Mach3 simply by touching the two together once connected to the pin and GND.

    Alternatively, the end mill can be connected to the pin and the plate connected to GND as long as there becomes a complete circuit when the end mill touches the plate.

    To setup homing for the Planet-CNC homing and limits, go to the Planet-CNC Machine setup page which explains the process step by step: http://www.planet-cnc.com/faq/machine_setup/
