Acceleration Tuning for Speed and Quality

Document the failure and confirm that it matches this guide: Fast direction changes cause echoing, noise, or lost position.

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

Check acceleration exceeds structure. Fix mechanics first.

Check belts or frame loose. Test in controlled increments.

Inspect input shaping not matched. Inspect ringing and shifts.

Rule out heavy toolhead. Save separate quality/speed profiles.

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.
