Jog issue

Hello

I’m playing with rectangular grid compensation.

After G32 and G28 we have to play with jog.

But sometimes (not every time) when I ask 0.100 mm Z axis, on official smoothieboard LCD panel or from pronterface, I get a movment of 2 to 5 mm, not 0.100 mm.

This is a random issue.

How to explain it and how to solve it ?

Thanks !
