Simple answer Is yes on the BUTTON and plugging in where to go...

The button can be done with a limit switch, wired normally open, and you'd hold it or whatever....

Mach has a MDI screen manual data imput... It is in g code form but THE CODES WOULD BE SIMPLE... like G1 X1 F50, Would be a feedrate movment of X 1 inch... None of that circular intrepolation g02 g03 and so on.. just G1 X,Y,Z,A,B,C F=feedrate in ipm/mmpm

So yes to all questions... No need for any extra scriting for the RED BUTTON...

I can't suggest which of the two mills you picked out might be better, I have never see one up close or used one..But I think that they both use Mach 3....
