Start with raise z offset in tiny steps, then clean and re-seat the plate. Confirm the result with a short representative test before changing additional settings.

Ordered repair sequence

Step 1

Document the failure and confirm that it matches this guide: First-layer lines snake, ripple, or change width as the nozzle moves.

Step 2

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

Step 3

Check z offset slightly too low. Raise Z offset in tiny steps.

Step 4

Check loose or contaminated plate. Clean and re-seat the plate.

Step 5

Inspect uneven mesh compensation. Re-run mesh calibration.

Step 6

Rule out first-layer speed too high. Slow the first layer and compare.

Step 7

Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.

Step 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.
