Question #: 14345

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

Current Solution

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).

  • 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.

  • Can the completely configured blueChick, with computer be shipped with working and test Unbuntu/EMC2 and not Windows/Mach3?

    I noticed in the Computer CNC Systems of this webpage that Linux/EMC2 (now called LinuxCNC) is available on the preconfigured systems. The wording on the CNC Machines page makes it look like Windows7 is all that is available. So thats the best I can see for now as far as clarity.

    Yes, if the redLeaf or redSprout is purchased with the machine, we can completely configure the electronics to use Ubuntu and Linuxcnc. If windows is selected, we install Windows 7 and completely configured under Mach3.

    If Windows is not selected, we assume Ubuntu/Linuxcnc, but we always contact the customer to confirm in these cases.

  • My computer does not communicate with AWC608 and LaserCAD

    If you are getting the "Communicating Unsuccessful!" error when you are trying to communicate between LaserCAD and the AWC608 Laser Cutter and Engraver controller (after you have already tried installing the USB driver from the LaserCAD setup procedure), these are the steps you will need for a successful communication:

    - Open the Device Manager window (right click on the start menu and select Device Manager)
    - When you plug the USB cable from the AWC608 Laser Cutter Controller (USB Type B connector) to the computer, you should see a new item in the Device Manager, possibly under "Ports (COM & LPT)", or under "Other Devices". It may show as an item under "Other Devices", possibly FT245R and has an "!" in a yellow triangle.
    - Download the latest FTDI drivers from: http://www.ftdichip.com/Drivers/D2XX.htm
    - Unzip the files to a folder that can be easily browsed.
    - Right click on the item that appeared in the Device Manager when the cable was plugged in between the Laser Cutter AWC608 controller and the computer.
    - Click on update driver
    - Select the procedure to manually install the driver and browse to the folder containing the FTDI driver and follow the step in the driver installation wizard.
    - The item should now be located under the "Ports (COM & LPT)" and should be named "USB Serial Device (COM#)". The # will be the number you will use in the LaserCAD software.
    - In the LaserCAD software, click the "Select Mode" at the far top right of the Laser CAD user interface.
    - Make sure USB mode is selected.
    - If the Machine name with the correct COM number is listed, select it and exit the dialog window. Otherwise, click on "Add" and fill in the details with the new COM number.

  • parallel break out board is not working-relay keeps switching my computer off when I power up

    Do you have anything connected to the relay?

    Additional Information:
    is the relay controlled by a pinout on the BoB?

    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

  • I am loking for a kit that can cut 4x8 material and would be ready to cut when assembled. plus what computer and software are needed to be ready to cut?

    The greenLean machine comes with the entire structure and features a 4'x8' cutting area. You will still need some hookup wire to connect the electronics and silicone tubing for the water to and from the spindle.

    greenLean Machine: https://buildyourcnc.com/item/cnc-machine-greenLean-v1

    Thanks for answering my last question. So I have two follow-up questions from the response. The green leaf stands vertical is it designed for the material to be cut without falling free once it is cut through? And second question: you metioned water running to the spindle is this a cooling system for the spindle?

    You would use holding tabs to keep the parts from falling out of the cut areas. Holding tabs are generated as part of the CAM file. Yes, this is the way the spindle is cooled. This is far superior to air cooling. Air cooling will blow the chips all over the shop.

  • IF MY COMPUTER DOESN'T HAVE A PARALLEL PORT, HOW DO I RUN THE MACHINE?

    If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

  • Lost Comm with steppers: I have been running Mach3 with my Black Toe for years. This morning, I booted up, motors locked up. Started Mach, hit reset, and nothing. Can't move. Checked plugs. Diag screen says OK. What to look for? I have the BYOCNC Computer/contoller box.

    New clues. I loaded a different profile I have used for another machine and my Black Toe moves. Of course all the settings are different. I load my normal profile and no ports, pins, or outputs light up.

  • MOTOR GOING TWO DIRECTION WHEN JUST PUSH UP. IT WILL GO DOWN AND THEN GOES AGAIN UP WITH THE SAME BUTTON.

    Try slowing your feedrate down and increasing spindle RPMs. End-mills will leave a poor finish if you go too fast. Make sure your cutting depth isn't too much. Maybe the endmill or cutter is blunt? Could it be the feed direction of the cutter? Some materials need to be fed in a certain direction.
