Input Shaping Basics for Cleaner Corners

Document the failure and confirm that it matches this guide: Echo lines appear after corners even though belts and frame are secure.

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

Check resonance frequency not measured. Fix mechanical play first.

Check mechanical looseness. Measure using supported method.

Inspect acceleration too high for structure. Apply conservative shaping.

Rule out profile mismatch. Verify with a ringing tower.

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.
