Repair sequence

Step completion

1
Document the failure and confirm that it matches this guide: Diagonal artifacts, skew, noise, or unequal belt tones appear on a CoreXY printer.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 unequal belt tension. Verify routing against official diagram.Not completed
4
Check incorrect belt routing. Inspect idlers and belt tracking.Not completed
5
Inspect idler friction or misalignment. Balance tension conservatively.Not completed
6
Rule out pulley fastener loose. Run square and diagonal tests.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
