Something's off?

Pick the symptom that's closest to what you see. Most fixes take less than 10 minutes.

The nozzle stops extruding entirely or produces thin, stringy filament. Carbonised gunk or wet filament is usually the culprit.

Corners lift off the plate, lines look gappy, or the whole first layer drags behind the nozzle. Grease and wrong Z offset are common causes.

Echoes and repeating ripples appear next to sharp corners. Loose belts or a wobbly table let the toolhead vibrate and leave ghosts.

Fine hairs and small zits appear on travel moves and surfaces. Wet filament and incorrect retraction or temperature are the usual suspects.

The AMS refuses to load filament or throws errors during mid-print changes. Tangled spools, worn cutters, and brittle tips cause most failures.
