Repair sequence

Step completion

1
Document the failure and confirm that it matches this guide: Hollow prints crack, deform, leak resin, or pull hard from the film.Not completed
2
Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.Not completed
3
Check closed cavity creates suction. Inspect hollow preview.Not completed
4
Check drain hole too small. Place low drain holes.Not completed
5
Inspect hole placed too high. Add a separate vent path.Not completed
6
Rule out no vent path. Verify wash access.Not completed
7
Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.Not completed
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.Not completed
