Repair sequence

1
Unload filament and inspect for grinding, deformation, or a tangled spool.Not completed
2
Check the complete filament path, tube, runout sensor, and spool movement.Not completed

Clean drive gears and set idler tension to the printer maker’s guidance.Not completed
4
Perform a controlled purge and inspect for curling or inconsistent extrusion.Not completed
5
Clear a partial clog or replace the nozzle if needed.Not completed

Return flow to profile default, then reduce speed/volumetric demand.Not completed
7
Re-test temperature and flow only after the mechanical path is clear.Not completed

Private workshop notes

No notes recorded.

Model: 100 mm extrusion and thin-wall test
Setup: Use the same nozzle, material and hotend temperature planned for the print.
Pass: Flow is smooth and the wall is continuous with stable width.
If unchanged: Clicking, gaps, pulsing or inconsistent line width remains.
