Thanks for the tips, @torgeir. I'm using brand new filament and have tried several with no change so I don't think that's the issue. Here are tests print from a g-code file UM sent me.

I tested the rod bearings and they looked good. Z nut something I can fix/replace? Thank you!!

Thank you both for the help. Tried (again) cleaning and oiling/lubing with no luck. Erin, I will be shipping you my printer soon as the box arrives.

@gr5 - I'm trying to remove the z stepper motor. Is it possible to remove the wires from the stepper directly or do I need to follow the wire to the main board(s)? They aren't sliding out from the motor easily and I don't want to force it if thats not the correct way. Many thanks!

Thanks for the quick reply. The lines do continue all around so I will try what you suggested and report back.

Hello, My UM2+ is having issues which seemed to be pointing towards under-extrusion. As such, after working with UM support and consulting countless posts on this forum, I ran through the normal troubleshooting, cleaning and lubing procedures and replaced parts (see below), I regret to say that the problem persists. My layers are uneven and my edges are not straight (see below). I rely on this machine and it's been down for almost 2 weeks. I would greatly appreciate help from you experts out there.
