Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.

I AM INTERESTED IN THE 3 AXIS COMBO USB OPTION. NOTICE YOU ENDORSE PLANET-CNC FOR USE WITH THIS BUT WILL MACH3 INTERFACE WELL BEAK OUT BOARD?

If you already have a Mach3 license, you don't need to purchase another one. The license is connected to you rather than the computer. Mach4 is licensed to the computer, but you are able to have multiple computers for each license, and can be switched from one computer to another.

If you purchased the license from me, you can call (make sure to leave a voicemail), or email to get a re-issued license.

[575] I have an older CNC (2018) which has been working fine. The Windows 7 PC crashed and I am trying to get operational again using a windows 10 machine. I will have to buy a new license for the Mach 3 so will need to get the interface board I have to talk to MAch 3. Can I get just the disc or is there a place I can download what I need?

Yes, you can use a conductive metal to serve as a zeroing block for the Z axis. All you need to do is connect the block (conductive metal) to one of the 4 inputs on the controller. The end mill must be connected to the DCM terminal (the GND of the 24V power supply) of the controller. In the inputs dialog box (config-ports and pins-inputs). Under the probe line, enter port 3 and the pin used for the block.

Is there a downloadable manual for the usb Mach3 interface board? I'm not sure one came with my Redleaf. Cheers.

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.

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?

I don't see why Mach3 under windows 64-bit wouldn't work with an interface that uses USB as it's primary communication method. I am a bit vague on this, so I will do more research on it.

We recommend Mach3 run under Windows 32-bit when using the parallel interface as this is a legacy function.

The USB interface only works with momentary switches unfortunately. If you have extensive knowledge of digital electronics, you can apply a receiver that uses a microcontroller and a transmitter with another microcontroller that produces the pulsing signal with the controls that you need.

Steel Sheet

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.

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.

MY COMPUTER DOES NOT HAVE A PARALLEL PORT. HOW DO I INTERFACE WITH THE BREAKOUT BOARD?

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

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.

The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

Additional Information:
I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

Additional Information:
Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

I have your Mach3 usb interface board and am interested in the relay board to turn plasma torch on/off. I have a different relay board that doesn't work, it needs 0/5v from output pin to trigger and the usb board doesn't put out 5 volts. Does this relay board need 5v on output or will work fine with this usb controller?

Yes, you can absolutely communicate with the Pokeys57CNC controller. The developer's website has various ways of control, including their poblock software, or directly programming using C#, or C++. I have tested the C# method for a job I did for Lockheed Martin and worked really well.

[596] Hi there! Thank you for your great works. I was wondering if there is a way to communicate with this board using custom-developed software instead of Mach3 or Mach4.

I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

Good evening, if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors. I have a 48V 12amp power supply. Thank you

I would recommend using a separate 24VDC power supply for the controller. The 24VDC that is connected to the controller is used for delicate input signals and output signals that control external devices. To keep interference and possible current and voltage fluctuations at a minimum due to the motor load, a separate power supply would be best.

[575] Can the 24VDC supply used for the interface board be the same supply used for stepper drivers, or do you need separate power supplies? If not, does GND and DCM need to be isolated?
