I'm almost 100% sure you need a firmware that can be manually controlled (1.1J on my da vinci 1.0) for the bed leveling wizard to work. It works for me, but I'm on a firmware that allows for manual control.
I tried the wizard and it seemed to get rid of the Z offset I had to set in Simplify3D. Does it store a value somewhere? I only had to do minor adjustments to the bed but the 2.98mm offset had to to be reduced to zero. I like it but I don't understand what happened. Like I said, I only made minor changes to the hight of the bed during the wizard, definitely not 2.98mm. Does anybody know for sure what it does in the software?
Isn't the point of the bed leveling wizard to remove the need for using an extra Z-offset? In my mind, if you successfully level the bed using that tool, then by definition your Z-offset should be zero.
