This Mach3 USB controller does not support THC functions. I would recommend using the Pokeys57CNC controller instead.

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.

Yes, this board supports THC functions. I have tested the Proma THC and the PlasmaSens which use fiber optics for communication to reduce EMI.

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.

Unfortunately, all of the attemps I have made to use this controller with a THC did not work, so I would not recommend this board for plasma machines that use a THC. THe Pokeys57CNC controller will work with several THC controllers. I have used the Proma and the PlasmaSens controllers with the Pokeys57CNC.

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.

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 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

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.

Yes, the Mach3 USB controller works with the Mach3 control software, one of the most popular control software for CNC machines. Fusion360 has a Mach3 post-processor.

Yes, the Mach3 USB controller can work with the Gecko G540 drives.

Here are the connections you will need from the Mach3 USB controller to the G540:
XP terminal to Pin 2 of the DB25 LPT connector
XD terminal to Pin 3 of the DB25 LPT connector
YP terminal to Pin 4 of the DB25 LPT connector
YD terminal to Pin 5 of the DB25 LPT connector
ZP terminal to Pin 6 of the DB25 LPT connector
ZD terminal to Pin 7 of the DB25 LPT connector
Any pins from 18 through 25 can be connected to the GND terminals next to the XP terminal.

Pins 10 through 13 can be connected to IN1, IN2, IN3, and IN4.

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.

You can adapt the Mach3 USB controller to control a laser, but I would not recommend it. A traditional laser controller that is designed to control a laser is far better since you can take advantage of more sophisticated features like sweep for engraving, and automatic adjustment of laser intensity for acceleration and deceleration. The Mach3 USB controller can move the axes and turn the laser on and off, but intensity control and engraving are not an option.

[575] Will this board operate a laser cutter and engraver

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.

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.

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.
