Resin Print Not Sticking to the Build Plate

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.

Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.

Check build plate not leveled. Re-level the plate.

Check bottom exposure too low. Clean it as specified.

Inspect plate contamination. Use resin-tested bottom exposure.

Rule out lift force too high. Reduce lift stress.

Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.

Compare the test against the target condition, record the successful value, and save it in a printer/material profile before repeating the full print.
