Jerk and Junction-Deviation Tuning

Document the failure and confirm that it matches this guide: Corners bulge, ring, or print with inconsistent speed transitions.

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

Check value too high. Identify firmware model.

Check value too low. Tune acceleration first.

Inspect firmware terminology mismatch. Adjust conservatively.

Rule out acceleration not tuned first. Compare corner test prints.

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.
