latest sample cuts from last night after running the auto servo tuning. Still not 100% but a cr@p-load better IMHO.

DOes it do this on EVERY small sharp corner? IF so then LOOK to the servo tuning, too much overrun will do it every time. The servo will overun the position and then back up to correct.
Just a thought, (;-) TP
One more thing, the Z axis sometimes moves DOWN instead of up when we hit zero all axis, now come the hell on, what the hell man!?!? I can't baby the damn machine ahole day, if I punch in a command I expect it to follow it now only follow it some times?!?! how can a person work like that?oh, before I forget, the Spindle only start up 75% time.
These sound like hardware troubles. What comes to mind is bad connections on the DIRECTION signal to the Z drive and spindle forward.
Does the DRO for the Z axis confirm the spindle is going down instead of up when you hit REF ALL HOME? I am assuming you mean REF ALL HOME since ZERO ALL AXIS should cause no moment.
