Watch for these signs
- bubbling at the nozzle
- popping sounds during extrusion
- stringing worse than normal
- rough surface texture
- weak layer adhesion

Container

Known Issues
Stringing
Cause: High temperature or insufficient retraction
Fix: Lower nozzle temp, increase retraction distance, add Z-hop
Blobs / nozzle buildup
Cause: Grid infill repeatedly crossing the same points; oozing
Fix: Use gyroid or cubic infill instead of grid; tune retraction
Poor bed adhesion on smooth PEI
Cause: PCTG does not grip bare smooth PEI well
Fix: Use a release agent / glue stick, or print on textured PEI
PTFE-lined hotend degradation at high temps
Cause: PCTG can run up to 260°C; PTFE liners break down above ~250°C, releasing fumes and restricting flow
Fix: Use an all-metal hotend when printing above 250°C
