General Mach Discussion / Re: Index pulse in Lathe

By Control I mean turned off and then on the computer and repeated the test.
Installed V3.042.033 just to discard a Mach problem.
I just ran a test with code generated with the threading wizard and the problem remains. The resulting thread has a fishbone shape. As the tool penetrates more in each pass it is also displaced a small amount in Z, therefore this shape.
I may have backlash, but I am sure its neglegible compared to error the thread is showing.
This behavior makes me suspicious of my Z axis setup. Will check that tomorrow.
