A1 mini printer - Extrusion stops completely at the same height. I need help! Hi everyone, I really need your help. My A1 mini stops extruding completely at the same height on this model. As you can see from the photo, the layers on the supports and boots are absolutely perfect up to that point. Then, extrusion abruptly stops with a sharp cut at the top, while the print head continues to move. eSUN Basic Black PLA, ambient temperature ~26°C, humidity ~55%. What I've ALREADY done: Tensioned the belts and fully calibrated the printer. Extruder gears checked and perfectly clean. Filament is dry (freshly dried). I downloaded a new print profile from Maker World. The part cooling fan is set to 100% (both minimum and maximum). What else should I do? I've already opened a ticket... (Photo attached)
