The Phase Stepping feature customizes the drive signal for each motor, customizing the drive signal for each motor. This addresses discrepancies like visible fine artifacts (VFAs) and noise caused by the natural variance in stepper motor manufacturing.

Accelerometer

The CORE One L does not need an accelerometer for the phase stepping, as it is already integrated in the nextruder assembly.

To calibrate Phase Stepping on the CORE One, an accelerometer set is necessary.

To connect the accelerometer to the printer, follow the steps from the dedicated accelerometer article.

Phase Stepping Calibration

The calibration shouldn't run on multiple printers side by side simultaneously. The neighboring printer performing similar motions may affect the measurement.

The phase stepping calibration is part of the starting wizard. To access the feature without the selftest, go to LCD Menu -> Settings -> Phase Stepping -> Calibration.

During the calibration, data from the accelerometer will be collected. The goal is to measure the characteristics of the motors and store these settings.

Calibration failed

If the Phase stepping calibration is interrupted and a "Calibration failed" message shows on the screen, check the printer's belt tension.
