since you are in contact to solve the problem, if they succeed in the thread (I doubt, give your evidence),
tell him to repeat the same empty cycle several times, because one of the main problems of the thread is that, if you repeat the cycle to reach the desired size, the previous thread is damaged or completely ruined.
but here I think it is Mach4's fault, and not Csmio.
I add another sore point to the thread.
if mechanical ranges are used, therefore with ratios, despite the correct compilation of the table in the spindle-related ratios, the wire pitches are totally wrong !!!
