sheetcam and mach3, how to start up plasma burner

Problems and questions
1

Hi there, i am new to plasma cutting.
I have connected a 220volt relay to the spindle port of my routers controller to fire up the plasma torch. That has worked with art cam created g codes.
I just set the spindle speed to full max.

With sheetcam created gcodes this method does not work.
The spindle is not activated, the relay does not click.

I tried to understand what part of the gcode actually triggers the plasma torch, could not figure it out so far…
In that art cam gcode it was “s” combined with a number for speed.

Anyway, can somebody help me out here? Do i have to change settings in shetcam or mach3 to get this running?

Thanks

What post processor are you using? For your setup you probably need the Mach3 plasma post.

SheetCam just uses M3 to turn the spindle on and M5 to turn it off. That should work. If you can’t find anything obvious, let me know what settings you are using in Config->ports and pins->Spindle setup.
