General Mach Discussion / Re: Axis stay short of where they should go

Mach will ALWAYS go the closest position it can go to the commanded point based on step size AND it does NOT accumilate error. IF it did then you would NOT have gone back to zero(;-) IF MACH has to hold short based on step size THEN at the next point it CAN it will add the hold short value back in.
I would guess that your steps per unit are not exactly perfect. When that is so then when you make a LONG move you see the error and when you move BACK to the start it will always be exactly where you started.
Just a thought, (;-)TP
