Where is backlash? I don't see it in general config. The shuttle accel is set on 1

Config menu then Backlash. You may have to restart Mach for it to take effect.

That seems to have fixed the problem. All axis move in fast jog with no hesitation. Thank you very much.

If you need the backlash you could reduce the shuttle accel and see if it helps, maybe 0.05 or something. Dont use backlash myself so not sure what the normal settings would be but I would imagine you want it a short time.
