In theory, utilizing a 5V reference in the 10V terminal of the Mach3 USB controller should yield functional results, although I haven't personally tested this configuration. If you possess an oscilloscope, you can monitor the PWM signal to verify whether the AVI output achieves a peak 5V PWM square wave.

What problems are you experiencing?

Additional Information:
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.

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.

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

Check that the port number in the outputs tab for the specific output you are using is set to port 3. Also, make sure you are wiring the output as shown in the outputs video below:

You can use two MGPs (bare MPGs) to provide independent axis control. The handwheel input on this controller contains discrete inputs for the X, Y, Z, and A axes. These inputs can receive a pulse to move their axis. For instance, you can connect an MPG to the X-axis pin and the wheel will move the X-axis only.

Of course, if you have a traditional pendant, you can move any axis independently from only a single wheel with a switch that selects the axis you wish to move.

[575] can we use two MPG for two axis independant axis movement

Open the input signals dialog box by clicking on config, then ports and pins, then input signals. For each line item that you use (i.e. x++, y--, etc) make sure the port number is 3.

Also, make sure there is a 24v power supply connected to the DCM and 24V terminals. One side of the NO on the limit switch must connect to the DCM, or the power supply V- terminal.

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.

Because the USB board is powered by USB (+5VDC) from your PC. Your inputs (eg. limit switches) require up to +36VDC to operate properly.

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.

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.

I have had no success with this controller paired with a THC
(Torch Height Controller) for plasma cutting. I would instead recommend the pokeys57CNC controller and the PlasmaSense and PlasmaSensOut THC controllers.

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.

The Mach3 USB controller will work with M3/M4/M5 or M7/M8/M9 combinations. M10/M11 is not available with the controller.

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.

You can use the mach3turn in the mach3 loader and simply enable the motor outputs. For the inputs and outputs, make sure to use port 3 for the port number and reference the terminal description for the pin number (i.e. IN2 is Pin 2). Don't forget to use the plug RNRMotion.dll in the plugins folder first.

I have not tried using the handwheel inputs for anything other than for handwheel operation. I haven't had success using a THC with the Mach3 USB controller. The pokeys57CNC controller is a better solution for THC (torch height controller) and plasma cutter use.
