G30 problem in 1.21
-
On my printer [c]G30[/c] seems to make the print head go back up 20mm after the probe.
Not only that but it sets the z=0 value way too high up.
[c]G30 S-1[/c] doesn't do that and the measured z seems fine.I'm about to revert to 1.21RC1 which I was using before and wasn't doing this. Can you think of a reason for this to happen?

I found my problem, looks like I had a bad bed transform loaded. Apologies.

I'm glad you found the problem. G30 with no other parameters now raises the head to the dive height after probing, like most G30 commands with parameters did already.
