Cutting deeper in areas???

No you need to set a Zero work position and return to that not Home position. Reason being that home position is referencing a switch so it will and should always return to that position.
Returning to Zero work position will tell you if you have lost position thru missed steps or slipping couplings etc.

But before all this have you Surfaced the Bed.? . . . . With fine engraving you can't have any error in the bed.!

Sorry, was on another plane there. Confusing my MCS with WCS, don't know if that is a common phrasing but that is what DSP refers to as the machine home position and the Work home/zero position. Yes I have returned it to the zero work position after homing and then drilled down with a 2mm drill bit, did this 10 times and was spot on each time??

So if I understand you, you are saying that it comes back to the zero work spot in X and Y as you are going down the same hole. But how are you testing the Z zero, is that coming back to the same spot. You could test this by setting work Z to say 10mm above the bed and checking it with a 10mm round rod or a spacer exact. Then run the machine and come back to work Z zero and see if the spacing is exactly the same. ..Clive
