Hello everyone. Having UM2 Extended for about a week already, and generally it's fine.. Except ABS clogging and one more trouble getting me every few prints. When I leave printer unattended, almost every time at the random layer, platform jumps a good 5 cm down ruining the print. Anyone had this issue? I searched and found only hardware-related issues. but mine seems fine when lowering/raising platform. Also I'm using cura and sometimes S3D when I need supports. It seems this happens while using S3D, but I'm not completely sure. Thanks in advance!
