Hi there!
We have installed an Buildtek Flexplate on our UM3 @work.
The problem with this setup is that automatic leveling does stop a bit too late so that the
first layer is pushed too hard into the bed.
Up to now we used the following startscript to increase the first layer height:
G91 ;Relative movement
G0 F15000 Z0.2 ; Move down the plate a bit
G92 Z0 ; Tell the printer that this is the zero position
G90 ;Disable relative movement
Unfortunately thi
Have you turned off auto bed leveling on your UM3?
I have read some posts about that, that after upgrading the saved values from the auto leveling are wrong and therefore the printer prints in the air because the offset is set to some phantasie values.
