Hi Daid,
Yep, replied on the other topic too. I was suspecting the residue was the source of the issue
Did cleaning the nozzle and bed help mitigate this problem?
A solution would be to drill 4 holes in the UM1 acrylic bed, get 4 screws and some bolts and assembly them in the following way (top to bottom).
Screw Head
Bolt
Bolt
Bolt
UM-BED
Bolt
Wire
Screw End
When homing the head we could use the Screw End touching on the ALU block used for nozzle heating rather than on the nozzle. The 3 bolts should be enough for this (otherwise just increase the number of bolts) and should constitute a "known" height.
Am I making sense?

Like I said in the other topic. I attempted this early in the UM2 development. Didn't work very consistently, due to residue on both the head and the bed you will not always get contact, causing the head to push into the bed way too far.
