Thread Milling Problems
When I attempt to run an old threading program (Mach 3 Wizards) my y-axis shifts about 4 inches. When I returned to the center (eyeball) of the 6 mm shaft both the machine coordinates center, and the dro centers are off by approximately 4 inches.
I also lose the ability to jog, unless the shift key is used.
If I reload the program, using the machine coordinates I can return to the center of the shaft.
I have generated a new g code using Mach 3 Wizards with the same effect.
If I run an old circle g code, everything seems to work normally.
Any ideas as to what's going on?
