Fix poor bed adhesion, lifting first layers, loose corners, and prints that detach from the build plate.
Start hereClean the build surface, confirm the correct surface for the material, then tune Z offset and first-layer temperature before adding glue or changing many slicer settings.
First safe actionClean and correctly seat the build plate before changing Z offset.
Proof targetA one-layer test joins evenly in the centre and corners.
Match the failed area to the visual before changing a setting.
Repair progress0 of 7 complete
Step 1 of 7
Wash or clean the plate using the surface manufacturer’s approved method; avoid touching the print area afterward.
Keep the problem and target visual open while you make this change.
Why this matters
Skin oils and residue can defeat an otherwise correct profile.
Setting or checkZ offset
Adjust only until lines merge cleanly; too low can obstruct extrusion.
Expected result
A full first-layer test stays attached across the plate.
Step 2 of 7
Run bed mesh or leveling, then print a single-layer test across several bed locations.
Keep the problem and target visual open while you make this change.
Why this matters
The lines sit on the plate instead of being pressed together.
Setting or checkFirst-layer speed
Use a conservative first layer so the filament has time to bond.
Expected result
Lines touch with no gaps and no raised ridges.
Step 3 of 7
Adjust Z offset in very small increments until adjacent lines touch without ridges or transparent scraping.
Keep the problem and target visual open while you make this change.
Why this matters
The material may need a different plate, temperature, or release layer.
Setting or checkBed temperature
Start with the material profile and move in small increments.
Expected result
Corners remain flat through the first 10–20 layers.
Step 4 of 7
Confirm the slicer selected the correct build surface and material profile.
Keep the problem and target visual open while you make this change.
Why this matters
A good Z offset in one area can be poor elsewhere.
Setting or checkBrim
Use for narrow contact areas, tall parts, or sharp corners.
Expected result
The finished print releases normally after cooling.
Step 5 of 7
Use a slower first layer and the filament maker’s temperature range.
Keep the problem and target visual open while you make this change.
Why this matters
Edges cool and contract before the base is stable.
Setting or checkZ offset
Adjust only until lines merge cleanly; too low can obstruct extrusion.
Expected result
A full first-layer test stays attached across the plate.
Step 6 of 7
Reduce early fan or shield the printer from drafts when the material requires it.
Keep the problem and target visual open while you make this change.
Why this matters
Skin oils and residue can defeat an otherwise correct profile.
Setting or checkFirst-layer speed
Use a conservative first layer so the filament has time to bond.
Expected result
Lines touch with no gaps and no raised ridges.
Step 7 of 7
Add a brim only after the mechanical and surface checks are correct.
Keep the problem and target visual open while you make this change.
Why this matters
The lines sit on the plate instead of being pressed together.
Setting or checkBed temperature
Start with the material profile and move in small increments.
Expected result
Corners remain flat through the first 10–20 layers.
