Repair sequence

Step completion

1
Document the failure and confirm that it matches this guide: The model exceeds the build plate or would require excessive support as one piece.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 cut placed on visible detail. Choose hidden structural cut planes.Not completed
4
Check no alignment features. Add keys or pins.Not completed
5
Inspect joint too weak. Plan joint strength.Not completed
6
Rule out tolerance not planned. Print a fit test first.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
