Can you tell me the correct way to wire tool probe on your Mach3 USB 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.

You're welcome

This will depend on the VFD you have to identify the correct terminal. The terminal on the VFD will be labeled AI1 typically (Analog Input #1). You will also need to make sure to complete the PWM circuit using the GND terminal on the VFD.

Additional Information:
I have wired my 0-10V signal to the AI1 and GND terminals as suggested. I have also set the PD-01 and PD-02 settings to 1. Still nothing. Is there something else that I am missing?

Additional Information:
Thanks for the information. Can you let me know the model of the VFD that you have?

Additional Information:
VFD Model # YL600-2S-2K20

Additional Information:
Thanks. I will check our resources and documentation to see if there is another programming setting that needs to be changed.

Additional Information:
Does your VFD have a VI terminal?

Additional Information:
No, it does not. The terminals for this VFD are as follows (seperated by dashes "-").

10V-AI1-AO2-PLC-DI5-DI3-DI1-COM
AI2-GND-AO1-DI6-DI4-DI2-FM-24V

Additional Information:
Do you have a PD070 parameter?

PD070 is the main Analog Input parameter.

The options for that parameter is:
0: 0-10V
1: 0-5V
2: 0-20mA
3: 4-20mA
4: 0-10V (4-20mA Stacked)
5: XIA
6: (VI+XIA)/2
7: (3VA+XIA)/4
8: (XIA_XIB)/2
9: Max (XIA, XIB)
10: Min (XIA, XIB)


Additional Information:
There is a PD-00 thru PD-09. PD-07 is currently set to 0.

Additional Information:
It appears that the manual I’m using “Titled YL600” is not the same as your unit. I will check our manuals and find the one that has only PD-00 to PD-09.

Additional Information:
For that VFD, the parameters are P0. The 0 may look like a D on the display.

The Mach3 USB board will fit in the redLeaf, but you may need to modify the Plexiglas top for proper mounting. However, the redLeaf has the proper parallel GPIO on the motherboard for use with the Parallel breakout board. If you have a laser on the machine you are using, then I would urge you to maintain the parallel breakout board as the Mach3 USB board will not work correctly using the Z-direction pin and you will need to determine how to use the output pins onthe USB board to ensure proper laser functionality.

Will Mach3 USB Interface board fit in my redleaf, in lieu of the breakout board that came with it?

No, you should not have received two parallel breakout boards in your CNC kit. You can return the extra item using standard shipping with COD. Our apologies for the confusion and the inconvenience.

The step and direction terminals on the Mach3 USB controller are the terminals labeled XP, XD, YP, YD, ZP, ZD, AP and AD. The P is the pulse or step terminal and the D is the direction terminal.

In our experience, the backlash compensation is not an ideal mechanism to solve backlash issues. It is best to resolve the backlash issue mechanically regather than through software.

Boards that handle all instructions on its own chip (which is the case for this all other USB boards) take some control away from Mach3. Without Mach3 having granular control. With that said, we do not have experience with the backlash compensation with that particular board. Our experience with backlash compensation with other boards have resulted in very poor accuracy and undesirable geometrical moves.

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, 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.

Yes, Mach3 (the software profram) will work with Windows 7, and windows 10 when coupled with the Mach3 USB interface. If you intend to use the parallel port driver, stick with Windows 7 in 32-bit mode.

The Mach3 USB interface card uses 5V (powered from the computer's USB) and a 24v to power the inputs, outputs and spindle control

the mach3 usb interface can be found here:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

But the mach3 usb does not absolutely need the 24V supply. The 24v supply is only needed if you will be using limit switches (I1-4), VFD controlled automatically and for use with the outputs (O1-4)
