Questions on using a moving gantry style mini-mill...

Disclaimer here .!! . . . You'll need to sort that discrepency in the Z axis if your having 0.3mm Skin so don't blame if your Z isn't fettled.!

Thats task no1, I will re-check it with the dial indicator as i cant see how it was going too deep. I know the bed is 0.1mm out of parallel over ints 400mm length but this was too deep at the point i set the tool using my probe plate.

My thinking is that I can set a tool, set zero height using the touch-plate, command G0 Z0.00 and run the cutter over the bed without any more than a witness mark?

The only thing i can see is the steps-per being off in Mach settings.

No2 job is fit and program the new VFD for sensors vector, might help a little, should certainly sort out that odd voltage issue on the 0-10v control, maybe even the lack of power at half speed.

No3 job is to run some tests on small scraps - i seem to have plenty now ;)

While doing all that I will be resigning my parts and maybe ordering some larger sheet stock so that it can be fixed down around the edges easier.
