I finally got my printer working again. I spent the whole day going through Teaching Tech’s calibration steps. All the flat calibration gcode looks fine. The Benchies are another problem though. I’m printing with a 0.6mm nozzle for the first time.
On the smaller benchy I printed at 0.2 layer height, with a perimeter speed of 40mm/s at 210/60 temps. The bigger one is 110% larger and printed at 0.25 layer height, with a perimeter speed of 60mm/s at 215/60 C.
The problems are mostly manifested in the same area. Big blobs in the rear and layer shifting on the tail pipe. Large layer shifts/bulges in the center. I’ve never really ran into this problem before so I don’t know where to start when diagnosing this.
Just wanted to say that I recently had a problem that turned out to be the hotend not being fully tightened and it was an absolute pain in the ass to finally figure it out. I swapped out a half dozen nozzles, changed my boden tubing, and eventually replaced my entire extrudor (not before playing with the tension a billion times).
Eventually discovered that the hot end wasn’t tightened and I was both immensely relieved and pissed off at the same time. Shit took me MONTHS to figure out.
I feel ya. Had that problem and was watching an unpacking and setup video for another printer when the person reminded me to go back and try that.
