Ordered repair sequence

Step 1

Remove the active spool and check it unwinds freely.

Step 2

Cut a clean filament tip and inspect for brittleness, swelling, or excessive curvature.

Step 3

Disconnect the path in stages to locate the exact resistance point.

Step 4

Remove broken pieces from tubes, hubs, buffers, selectors, and extruder entry.

Step 5

Clean feeder rollers and confirm PTFE tubes are fully seated.

Step 6

Test the same filament in another slot and a known-good filament in the failing slot.

Step 7

Use approved spool adapters or support for incompatible spools.

Step 8

Complete several load, purge, and unload cycles before a long multicolour print.
