Hello,
I've been using my UM2+ for months without issue until last night. A print started out great and looked like the first several layers printed perfect, as did the last several it seems, but in the middle there is a great deal of under extrusion going on. The model in Cura 2.3.1 looks good, no red in the x-ray, and the layer preview looks good as well. But why would it really under extrude in the middle but not the end? I can't figure out if this is a hardware or software issue. I have the g-code available to preview. Attached are the Cura settings, the layer preview, X-ray, as well as images of the final print. I scaled the part to 125%, used the basic Normal quality default settings, but changed infill pattern to Tetrahedral, and enabled supports only touching build plate.
Does anyone have any ideas if this is hardware or software?
