All the filament i tested today was previously dried in a food dryer and stored in vacuüm bags. I think i found the issue on one of them in the extruder idler gear axle which had came out of the handle at one end. I guess the jerks on the extruder make it work it’s way out through vibrations, causing the extruder to lose it’s grip on the filament causing under extrusion. I printed a small plate and glued it on the handle to prevent the axle from working it’s way out again. Benchy are printed fine again in different filaments, now started something bigger. --- _[View the full topic](https://forum.sovol3d.com/t/suddenly-poor-print-quality-on-two-sv08s-solved-with-extruder-idler-gear/5856)._
