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.

Mach SDK plugin questions and answers. / Re: MPG and Jog ignoring metric units

Mach SDK plugin questions and answers. / MPG and Jog ignoring metric units
« Last post by Userli on February 13, 2026, 10:32:16 AM »I'm developing a MACH4 plugin for a pendant, which uses MPG and JOG movements. MACH4 is configured to use metric, including jog units and I set mcJogSetUnitsMode(m_inst, axisId, MC_UNITS_METRIC) in addition.
Still when using mcJogIncStart or mcMpgMoveCounts the device moves 1 inch (i.e. 25.4mm) instead of 1 mm per unit passed to the methods.
I tested this on versions 6778 and 6693.
Is this a bug or am I missing a configuration?

M31 Motion Controller / Re: M 31 stepper wiring
« Last post by paul.stephens on February 13, 2026, 08:49:40 AM »Hi Ed,
For your G540, you will need to break out your DB25(Parallel port) and connect the following pin wires to the following connectors.
X Axis
DB25 Pin 2 → M31 MTR0 S+
DB25 Pin 3 → M31 MTR0 D+
Y Axis
DB25 Pin 4 → M31 MTR1 S+
DB25 Pin 5 → M31 MTR1 D+
Z Axis
DB25 Pin 6 → M31 MTR2 S+
DB25 Pin 7 → M31 MTR2 D+
A Axis
DB25 Pin 8 → M31 MTR3 S+
DB25 Pin 9 → M31 MTR3 D+
Below is your manual for reference:
https://www.geckodrive.com/wp-content/uploads/2023/04/G540-MANUAL-REV8.pdf
You can use a Ohm meter to test continuity on your pins if needed to find which wire is which pin.
Alternatively, they make DB25 Breakout Boards.
Thanks,
Paul

« Last post by Tweakie.CNC on February 13, 2026, 12:54:33 AM »Hi Ed,
Perhaps I am misunderstanding your comments but you cannot connect stepper motors directly to the M31.
The M31 is a ‘Motion Controller’ in exactly the same way that the Warp9, ESS is a ‘Motion Controller’ – they each require drivers (such as the G540) to operate the motors.

M31 Motion Controller / Re: M 31 stepper wiring
« Last post by paul.stephens on February 12, 2026, 03:27:33 PM »Hi Ed,
Wire colors are superficial and thus tend to mean nothing. There is somewhat of a standard, but those standards can change from person to person or company to company. This makes going off of wire color VERY unreliable.
What Drives do you have?
thanks,
Paul

« Last post by edcross on February 12, 2026, 05:32:41 AM »I am not using the G540 any longer. Are all 4 wires from the motor used , I do not know where each colored wire should go on the connector
that is my problem , the manual does not state that ( blue to ? red to ? etc) Also vfd wiring .
