Quick diagnosis
Clean textured or smooth PEI sheets safely so first layers stick without damaging the surface.
Likely causes
- Skin oils on PEI
- Residue from glue or filament
- Dust buildup
- Prints removed while too hot
Step-by-step fix
- Wash with dish soap and warm water.
- Avoid touching the print area after cleaning.
- Use isopropyl alcohol for quick wipe-downs between prints.
- Let the sheet cool before removing prints.
What to check before changing more settings
Only change one variable at a time. Save your current slicer profile before testing, use a small repeatable test print, and compare the result before moving to the next adjustment.
