Repair sequence

Step completion

1
Document the failure and confirm that it matches this guide: Filament stops before the nozzle, bends at the feeder, or never reaches the hotend.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 cut end is blunt or bent. Cut a sharp angled tip.Not completed
4
Check extruder path is misaligned. Open the idler and align the path.Not completed
5
Inspect ptfe tube obstruction. Inspect the PTFE tube.Not completed
6
Rule out hotend not at loading temperature. Heat to the material load temperature.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

Observations and winning values

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.
