Mach4 General Discussion / Mach4 - C82 - PlasmaSensOut - Z axis

« Last post by grivalsky on February 16, 2026, 04:02:15 PM »

I have Mach 4 - hobby, C82 - dual-port multifunction board - torch height control - PlasmaSensOut
I had installed and purchased a hobby license.
Mach4Hobby_Installer-4.2.0.4612
ESS_Mach4_v278.1
The X axis, Y axis and Z axis worked correctly. When I connected and turned on the HC
the signals for the HC come to me and I see them on the screen as the indicator light lights up, but the Z axis does not respond to them. Even though I have the HC switched to manual control, the Z axis does not respond.
I tried everything I could think of but the HC did not work.
I uploaded a new plugin, I did not change anything, I just uploaded a new plugin there
ESS_Mach4_v320
The X axis, Y axis worked correctly but the Z axis does not move at all even when I turn off the HC. At least the Z axis worked with the 278 plugin.
When I put plugin 278 back in, my Z axis starts working again.
1. Can you tell me what changed that made my Z axis stop working after uploading the new plugin. And how do I fix it?
2. Why doesn't my HC work at all?

M31 Motion Controller / Re: VFD

Your motion controller should be the M31 and the active motion controller should be the M31. In the M31 plugin, you will need stepper motors selected as well as your indexing to be correct. (For steppers, Motor0 is index zero Motor1 is index 1)

What is your current motor wiring for the M31 to your G540?

I am sure glad you are on this forum , i am not getting much response from support . On the drive problem i got a db25 board and  just connected my G540 , no movement i will go over the settings . What should it list as the control source in the config window.

       Thank you

You will need a SOURCE wiring Configuration for your VFD.

In such wiring mode, remove the jumper between +24 V and OP. Connect +24 V to
the common port of external controller (J5 FE on the M31) and meanwhile connect OP to COM. If external
power supply is applied, remove the jumper between CME and COM.

This will be your forward signal:
VFD+24v → J5 FE M31
VFD DI1 → J5 FC M31

This will be your Speed adjustment:
VFD AI1 → J5 10v
VFD GND → J5 0v (Verify this is the correct ground by reading your VFD manual)

MachPro General Discussion / MachPro

« Last post by cd_edwards on February 15, 2026, 03:10:25 PM »

For anyone thinking about upgrading to MachPro there are still issues being worked on. I have problems with reading Registers from m-code scripts. For me, and the RC ATC this is a problem I need to solve as I need a removable dust boot. As far as the program, it's nice... There are definitely QOL improvements over Mach4 and way beyond Mach3. ESS support appears to be working extremely well. Definitely some niggling little bits that need work at this time though. It is unforunate that Mach4 is being EOL'd at this time though. Maybe a discount given to those that already own Mach4 might be an option. I've spoken to Carl Eldridge on the phone and he seems like a great guy. I wish them ALL the success the in world on this endevour.

As far as the hardware I can't speak to it, but with all the ESS and cnc4pc parts I have kicking around, there was no way I could justify moving to the M-31.. Ethercat would be really nice, but it's also out of my budget as a hobbyist. Right now I'm working on my fourth CNC build in 15 years. I will be moving it over to MachPro once a few features are working. RC ATC, maybe script debug, IPC would be nice so that remote control is possible (almost working).

I would like to see them finish Mach4 so it's more usable. IPC on my win10 and win11 computers fail. This affects wxprobe screen which does not work at all for me. They have this great probing screen that's useless as it won't detect probes at all. :shrug: 

anyways, if anyone has ideas on why mcGetRegister() fails in a m-code script, I'm all ears. return code can be -17 or -27(??) occasionally, and sometimes 0 for rc. always 0 for value.

Spanish / Usar comandos Rest API

« Last post by Sergi on February 13, 2026, 12:50:08 PM »

Hola buenas tardes,

Hay forma de usar comandos Rest (Get/Post) desde Mach3? He probado varias formas  que si funcionan en Vb pero no en Mach3 ya que creo que es porque le faltan librerías y da error.


Gracias de antemano.

I should have added that the increments are set to 1. The GUI exposes the same problem when jogging.
