I solved the problem by doing a few things: First, my extruder motor was loose -- the screws must have loosened over time due to vibration -- so my motor wasn't making reliable contact with the main drive gear. I tightened the bolts and will check them regularly. Second, I calibrated my cold end at your suggestion by following this Thomas Sanladerer video guide. Third, I replaced my Chinese knoby elahd - Printing
Thanks for the advice. I damaged the trim pots on one of my stepper drivers. I'll give your suggestions a try when the replacement arrives.by elahd - Printing
Lower the acceleration on the axis on which you're having the problem. In Marlin, this is the DEFAULT_MAX_ACCELERATION setting. Bring it down to 500. If that fixes the problem, raise it incrementally until you find a good balance between quality and speed.by elahd - Printing
Hi-- I'm running into issues with inconsistent layers, as seen in the photo. The picture is of the idler on the Prusa i3 Rework Extruder Upgrade. I've tried: * Extruder temperatures between 185 and 210 C. * Print speeds between 20-40mms for perimiters / 30-60mms for fill * Extruder DEFAULT_AXIS_STEPS_PER_UNIT between 550 and 600mms * Cura's cold head lift function at 8 seconds minimum per layeby elahd - Printing
