Controller Circularity Test

Start the circularity pass and rotate the left stick around the full gate. The canvas shows range coverage and circularity error for diagnosing worn analog sticks.

Why Circularity Matters

Some sticks center correctly but fail to reach full travel evenly. That can affect racing, fighting games, camera control and aiming sensitivity.

For best results, rotate smoothly several times and avoid snapping between corners. Compare coverage and error before and after cleaning or repair.

Circularity Workflow

Use circularity after a drift sample to understand both center offset and outer-gate travel.

Start Pass

Begin the timed circularity sample.

Rotate Smoothly

Move the left stick around the full gate.
