My direction is ok , it all travels the correct steps per. its literally when I have told the depth to go to -0.100mm the dro reads -0.0996. Iknow its very very little but Im trying to engrave tile which as I have just found out is not even close to being flat.

Ok, those numbers are different from what you posted the first time.? -0.1 is a long way from 0.996 which is closer to 1mm, however, the error you are seeing is common in Mach 3, it's a rounding up type error and I doubt your machine can resolve to 4 digits, very few can, so I wouldn't worry about it.
