Hmm,
Without that G04 the Z emits a very short screech, but at a point when the Z should not be moving at all - right at the beginning? I could maybe video this as it is repeatable.
G0 over a sort distance just seemed unnecessarily hard, time saved is nil, so why beat the machine up doing a short pair of rapids when a smooth co-ordinated move is better
Can't be losing steps - this is a DRO issue only, not physical, I have not got as far in testing yet to prove lost physical steps, just that the DRO does not always return to zero which seemed odd as that was where it came from But if as you say it is made up then no worries at all, even if its not 0.1mm is bugger all in the real world, metal expansion is probably a bigger issue
The button changing Z is worrying as Z definitely changes, again, I could video this action.
