Nextruder Feeding Issues
The Core One's Nextruder is the same design as on the MK4S, so the MK4 Nextruder guide applies in full.
Quick checklist:
- Is the idler lever fully closed?
- Is the filament end cut clean and straight enough to pass the sensor?
- Is the nozzle partly clogged? Try a cold pull.
- Is the chamber too warm for PLA? Heat creep shows up as clicking mid-print.
