Quick diagnosis
Stop PLA corners from lifting by improving bed grip, reducing cooling shock, and using brim or mouse ears where needed.
Likely causes
- Drafts around the printer
- Bed not clean
- Small contact area
- Cooling too aggressive early
Step-by-step fix
- Clean the bed thoroughly.
- Use a brim for wide flat parts.
- Reduce first-layer fan or delay full cooling.
- Check that the bed temperature is stable across the print surface.
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.
