Hobbyist here in Tampa, been doing more engraving lately and noticed a minor issues. I began to notice the engravings were much larger than in the design. As you can see in the attached pics, the actual part does not match the preview, note the center of the 6. It appears the tool is going deeper than it should. I am running and older PRT with a G4 upgrade. The Z axis seems to be dead on whenever I check a move. After I ran the part the zero was still zero. The start location is zero on the tool path. The tool was a 90 degree just as specified on the tool path. Not sure where to go next. Any help would be appreciated.
