After roughly 150 hours of use, the prints from my Taz4 have developed misaligned/sheared/lopsided layers. According to my research it may be due to skipping steps, which can be caused by potentiometer settings, belt tension, or loose set screw on the pulley or not on the stepper shaft.
I’ve leveled the x axis from the y aluminum plate under the glass bed. The bed_calibration.gcode file from the SD card prints perfectly. I’ve tighten every screw I can find. The belt tension is ideal. I’m very confused and hoping to find some help here.
To be honest, I have no clue where to start in regards to potentiometers. Are they adjustable via the LCD control settings?
As for the set screw on the X axis motor pulley, without a schematic I can’t be sure if I have tightened it or not. Can anyone include a picture of this set screw, and how it should ideally be tightened to the motor shaft?
Included are pictures of the issue I’m encountering, and orthographic renders of the intended shape:
