Look at your G code to see if your Z moves are -Z.010 you need to have a negative number

z0 is normally the top of the part in most cases
if you want to cut into the part the value has to be neg. z1.0 is one inch above. assuming inch's on mill and not metric.


If you DRO is goes from 0 to 1 and your cutter is going down, then your direction in mach is backward for that axis.

"G0 Z-1.0000" is the correct code to go down 1mm or inch on a mill in Mach3. The other option is to reverse the axis direction in the setup.
