Repair sequence

Step completion

1
Document the failure and confirm that it matches this guide: Filament snaps inside the feeder or cannot be unloaded normally.Not completed
2
Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.Not completed
3
Check brittle or moisture-damaged filament. Release feeder tension.Not completed
4
Check sharp path bend. Remove all fragments.Not completed
5
Inspect excessive gear pressure. Check spool condition.Not completed
6
Rule out heat migration. Inspect path bends and heat.Not completed
7
Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.Not completed
8
Compare the test against the target condition, record the successful value, and save it in a printer/material profile before repeating the full print.Not completed

No notes recorded.

Verification test

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.
