Print Bed Wobble and Loose Carriage

Document the failure and confirm that it matches this guide: The bed rocks when touched or changes position during acceleration.

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

Check loose v-wheels or linear bearings. Check play with power off.

Check bed screws or spacers loose. Adjust carriage preload.

Inspect worn wheels or bearings. Tighten bed hardware evenly.

Rule out cable strain. Verify cable movement.

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.
