When specifying a gear_ratio it is preferable to specify the actual gears on the mechanism (eg, prefer gear_ratio: 80:20 over gear_ratio: 4:1 ). And I assume not by a (whatever) buffer overflow. Cold extrusion prevention was the first thing that came to mind. The best nozzle temperature for PETG ranges anywhere between 220-250°C depending on the brand of filament you have, plus your specific 3D printer and setup. PrusaSlicer的起始G修改. 4. It looks like under-extrusion but the bottom is perfect. Changes in extruder output can be detected by monitoring the pressure at the entrance to the die. I recommend cross posting the problem and solution, when you have it, in the Neptune 3 sub. Use the main klipper branch. It's an ender 3 pro upgraded with an skr mini e3v3 and a revo cr.
