Sorry to hear you are having issues. Couple of things that will help get you on your way. If you can list what table you have, what software you are using, what plasma (cutter) you are using and what the actual problems are (the more detail the better) or even pictures, we can chime in and help get you going.

PWM is used for Spindle Speed. PWM is an option in MACH settings. Has noting to do with motion or plasma cutting. Its in the Spindle settings . It means the speed called in the gcode is less than the minimum you have set in the PWM spindle settings

Hayman,

I think I know what the problem is.

Go into Mach3 >> Config >> Ports & Pins >> Spindle Setup Tab

It will look like the attached.

I suspect that as I've shown, "PWM Control" is ticked.

If that is the case, untick "USE Spindle Motor Output" and it should work fine now.
