I have purchased Cetus MK3 standard version last December.
Since then, all up hill. Its hard to print a component, its grinding filament and not passing it through the nozzle causing prints failure. It is getting to very frustrating moments as since I have the printer, I have used 5kg of material while, maybe, I got only 1kg of successful prints.
Printer prints raft, goes for about 1h and stops, than only moves around without extruding.
I have tried 4mm nozzle and 6mm nozzle without any success. Both softwares, UpStudio and UpStudio3. No difference. Please see pictures, the bearing next to extruding gear has made a mark on the extrusion stepper motor, is that normal ?
Printing parameters are as follow
0.2mm layers height
1.75mm PLA (Esun, Sunlu, Tiertime) no difference, same result an all.
Is there something fundamentally wrong with my printer ? how can I get it to work?
