What version of software are you running looks nothing like my screens for plasma cutter, looks like you may need to update to Version R3.043.066 just corrected your code and loaded into that with no problems.

190mm and you go to the Artsoft site and download latest version and install it thats why you buy a licence for updates and support.

Worth checking that "steps per" settings are correct in Mach3? Or do gcode files from other CAM packages work ok?

It is a full version I just do have the details.It seem like a old version

You can download latest version for free, when you install if licence is valid its unlimited and if not it limits to 500 lines I believe.

For motor tuning I set and save a value and then manually command a small move of a couple of mm, fiddle with the tuning until that's close then play with larger moves, working up to something close to full travel.
That way you aren't making any assumptions or guesses,
