if i tighten the screws nearly completely, the procedure works again. Thanks.
However, i would wish that the programming of active levelling is more robust. It seems that you do not check at the start of the procedure if the plate is nearly in contact with the plate. Or why not use the z-height of manual levelling as starting point.
If i use -for example- the "BuildTak FlexPlate" on this UM3 the start distance is again too tight and active levelling fails again.
Thanks for help.
I think during manual leveling the total distance between the top and bottom of the buildplate has gone outside of specifications (there is an end to what we compensate for)

Make sure that your buildplate bottom and top are approximately 14mm apart.
Then manual level again.
Then try again.
