Thank you for taking the time to read. I am new to mach3 and my new to me 6040. It seems that I have my machine running mostly other than this issue. When running my first code. A facing operation, my machine moves from 0,0,0 (Top face center) to the corner of my workpiece. Then the tool lifts about 3 mm to do the rest of the operation. The DRO shows z is at 0 still though. IDK I am coming from GRBL and never had this issue, also I was able to run the same gcode in Drufel with out this issue. It is probably simple but I just have no idea.
