Babystepping effect on Z limit and jog controls
-
I just encountered this recently while lazily tuning z probe trigger height. I'm using a printer with a moving Z axis for reference
During a print, babystepping works as intended, but I noticed that it has a reversed effect on the Z limit when using the jog controls when not printing.
If I set the babystep offset to +0.15mm and then jog the bed positive and then negative back to it's limit, it will actually let the bed come up to -0.15mm as reported in status/tool position.As everything works during a print as it should, this isn't actually an issue. I encountered it largely by accident while using babystepping on a test print. I had assumed that if I moved the Z axis to it's limit with the jog controls after the print, I would be at my babystepped height.
Really just curious what the interaction of babystepping is with Z0 limit and why it gives a reversed effect.

Firmware versions?
I clear babystepping at the end of a print so I can't say I've noticed this behaviour at all.
