Question #: 15427

Question: [Mach3 USB Interface Board] Does this motion controller support Backlash Compensation?

Current Solution

This controller lacks the capability for backlash compensation. While software or signal-based adjustments are feasible, they are far from optimal if the controller natively supports backlash compensation. The most effective way to address backlash is through the mechanical components of the machine itself.

  • [575] Does the USB MACH3 controller support Sherline 1/2 pulse mode?

    The Mach3 100 kHz controller may be able to support the Sherline 1/2 pulse mode, but I have not tried it. There is no information in the documentation that is related to the parameter that can be set in Mach3 for the Sherline 1/2 pulse mode. You may be able to play with the available kHz ranges that the plugin allows to see if there is a pulse width that meets the Sherline 1/2 pulse mode specification.

  • [575] Does this board support indexing on mach3 turn? Planning to use it on a lathe and will do threading jobs

    You have the ability to designate the 4th axis, commonly known as the A-axis, for rotary indexing operations when using a Mach3 USB controller.

    To achieve this in Mach3, you'll need to:

    Open the Mach3 software.
    Navigate to "Config" and then to "Ports and Pins."
    Go to the "Motor Outputs" tab.
    Enable the A-axis and assign the respective Step and Direction pins.
    Save your settings and exit the "Ports and Pins" dialog.
    To calibrate the A-axis, go to "Settings" and use the "Set Steps Per Unit" option.

  • [575] Hello. Does this USB interface board thc? I have the proma 150.

    I do not recommend using the Mach3 USB controller to be used with a torch height controller. There are only 4 inputs on the Mach3 USB controller. We have tried to interface a Proma THC to this board without success; however, we did not exhaust all possibilities.

    I would recommend the Pokeys57CNC controller to connect the Proma THC as I have interfaced these two before and they work well together.

  • [575] Instructions read 24v on the card, can it support 36vdc ?

    The power supply that is used to power this controller must be 24VDC maximum. Any higher voltage and the controller components can be damaged. The 24VDC power supply doesn't need to be a high amp power supply. I would recommend This power supply: https://buildyourcnc.com/item/electronicsAndMotors-power-supply-24v-1a-dc

  • [575] Will the Mach3 USB interface board support other software such as Easel?

    The Mach3 USB controller is specifically engineered to integrate seamlessly with Mach3's CNC control software. Easel, on the other hand, offers an all-in-one CAD/CAM solution along with machine control capabilities. While Easel can output standard G-code compatible with industry-standard post-processors, it can serve as a design tool when used in conjunction with Mach3 but not as the machine control software.

  • [575] The older B.O.B. needed a charge pump as an added safety feature, does this U.S.B. board need a charge pump?

    The pulse stream is output directly from the onboard microcontroller on the Mach3 USB controller, so there is no need for a safety charge pump from the computer to the controller. Parallel port breakout boards were connected to the computer via GPIO pins (General Purpose Input/Output) and each pin dedicated to the step pulse would be output directly from those pins. In that case, a safety charge pump was needed.

  • [575] Hi, I have an old version of MACH3 V1.84 - Can someone tell me where to place the USB motion drive as there is no plugin folder in this version.

    Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

  • [575] Do I have to use the motion driver and configuration file to use this card? The x,y,a shows that it's moving on display, but the motors aren't moving.

    Yes, the RNRMotion.dll file must be used and put in the plugins folder under the Mach3 folder.

    The XML file that I link on the Mach3 USB controller page is the file you should start with. This file will have the necessary configuration that links the Mach3 USB controller to the Mach3 control software. You can then make whatever changes you need to this configuration to tailor it to your machine.

    Do you see a quick flashing red led on the board when you press the arrow keys?

  • [575] After reset of E stop, I get error message "RnR Motion Card Not Found". Have you any advice?

    If you are getting the message RNR Motion Card Not Found, the controller is shorting. Check the wiring to make sure you have all of the correct wires in the correct terminals. Check the voltages of all the terminals to make sure everything shows the correct polarity and voltages.

    Additional Information:
    Mine did the same thing. Try pushing the USB cable all the way into the port and slightly up. My usb port on the card is slightly oversized and breaking the connection. Ordering some USB type B connectors off of amazon, gonna try and re-solder a new port on the card before replacing the card.

  • [575] Will this work with Mach4. I,m thinking to upgrade from Mach3.

    The Mach3 USB will not work with Mach4. Consider the Pokeys57CNC controller instead. The Pokeys57CNC controller will work with Mach3 or Mach4 and contains more features than most CNC machines need, including 8 motor outputs, 4 onboard relays, limit home and probe inputs, galvanically isolated outputs, and much more.

  • [575] Hi, Can I use this board with a closed loop stepper?

    Yes, this CNC controller can be used with closed-loop stepper drivers and motors. The loop for control and feedback is between the driver and the motor. The closed-loop driver receives step and direction signals, which this controller will output which furnishes the driver with the necessary signals to move the motor. Additionally, the closed-loop driver can output a fault signal to this controller through the controller's input terminals in case the motor should encounter a situation that prevents the motor from moving so the CNC can shut down.

  • IS IT OK TO LEAVE THE VACUUM PRESSURE CONTROLLER PLUGGED IN ALL TIME WHEN PUMP SWITCHED OFF?

    I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

  • LASER CONTROLLER PASSWORD?

    What is the model number of the laser controller?

    Additional Information:
    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.

  • I'M CURIOUS IF THESE SYSTEMS WILL ENGRAVE LETTERING ACCURATELY WITHOUT BACKLASH?

    The machines have minimal to no backlash depending on how you apply the machine. Since the cnc machines use roller chain on the x and y axes, and the roller chain is tensioned, the backlash is nearly eliminated. I say nearly because the if you control the machine in a way that there will be excessive load on the end mill, then the machine could have a tendency to spring to one side or the other because of the length of tensioned roller chain. The movement is minor and can be eliminated with the proper control of the machine.
