[Help noise from UM3Ext]

Hi all.

I can't figure out how to fix this.
I keep hearing an annoying noise that seems to come from the seat belts or seatbelt pads, but I cannot identify it.
I've lubricated the axles and tightened the belts but it doesn't work out.
Do you have any ideas?

 

 

Thanks

[UM3 NOZZLE 2 always leveled too close to bed after active leveling]

I have the same problem on my UM3 Extended bought 3 days ago. I currently solved by installing the z offset plugin.
Can I send you the log files?

[2nd nozzle too tight to glass plate]

Hi everyone, 
IM becoming crazy! I just bought UM3 Extended and everything works perfectly with the first print core.
I am trying to print with PLA using ONLY the 2nd print core, but nothing to do. I leveled by hand, then I made numerous active levelings, but the result is always the same: the nozzle of the second print core, after producing the blob correctly, does not print because it is too tight to the glass plate.
If I try the first one core and everything is perfect.
I searched for an offset Z, but there is nothing ...
Can you help me understand what to do?
