A detailed STLBEAST repair guide to restore bottom-layer adhesion without excessive exposure. Learn how to recognize the symptom, rank the likely causes, apply safe fixes in order, verify the result, and prevent the failure from returning.
Start hereStart with re-level the plate, then clean it as specified. Confirm the result with a short representative test before changing additional settings.
First safe actionConfirm plate leveling, resin temperature and release conditions first.
Proof targetA small validation print remains attached and completes cleanly.
Match the failed area to the visual before changing a setting.
Repair progress0 of 8 complete
Step 1 of 8
Document the failure and confirm that it matches this guide: The raft remains in the vat or only part of the model attaches to the plate.
Keep the problem and target visual open while you make this change.
Why this matters
The initial gap differs across the plate.
Setting or checkNormal exposure
Tune for detail and layer strength at the actual resin temperature.
Expected result
The raft bonds evenly and supports the model through the full print.
Step 2 of 8
Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.
Keep the problem and target visual open while you make this change.
Why this matters
The first layers do not cure strongly enough.
Setting or checkBottom exposure
Use enough for adhesion without excessive base growth.
Expected result
The same test succeeds at least twice without a new artifact appearing.
Step 3 of 8
Check build plate not leveled. Re-level the plate.
Keep the problem and target visual open while you make this change.
Why this matters
Residue prevents bonding.
Setting or checkLift speed/distance
Control peel force and allow complete release.
Expected result
No safety warning, unusual noise, heater error, binding, or material damage is introduced by the change.
Step 4 of 8
Check bottom exposure too low. Clean it as specified.
Keep the problem and target visual open while you make this change.
Why this matters
Suction peels the raft away.
Setting or checkSupport/contact size
Match the cross-section and suction forces of the part.
Expected result
The successful values are recorded with printer, nozzle, material, slicer, and date.
Step 5 of 8
Inspect plate contamination. Use resin-tested bottom exposure.
Keep the problem and target visual open while you make this change.
Why this matters
The initial gap differs across the plate.
Setting or checkNormal exposure
Tune for detail and layer strength at the actual resin temperature.
Expected result
The raft bonds evenly and supports the model through the full print.
Step 6 of 8
Rule out lift force too high. Reduce lift stress.
Keep the problem and target visual open while you make this change.
Why this matters
The first layers do not cure strongly enough.
Setting or checkBottom exposure
Use enough for adhesion without excessive base growth.
Expected result
The same test succeeds at least twice without a new artifact appearing.
Step 7 of 8
Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.
Keep the problem and target visual open while you make this change.
Why this matters
Residue prevents bonding.
Setting or checkLift speed/distance
Control peel force and allow complete release.
Expected result
No safety warning, unusual noise, heater error, binding, or material damage is introduced by the change.
Step 8 of 8
Compare the test against the target condition, record the successful value, and save it in a printer/material profile before repeating the full print.
Keep the problem and target visual open while you make this change.
Why this matters
Suction peels the raft away.
Setting or checkSupport/contact size
Match the cross-section and suction forces of the part.
Expected result
The successful values are recorded with printer, nozzle, material, slicer, and date.
