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.

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 -> Control -> Calibrations & Tests -> Phase Stepping Calibration.

The printer will move the print head (in the case of the Multi-Tool it will select the first print head) to the middle of the bed and move the tool diagonally for the X and Y axes at different speeds. During that time, data from the accelerometer located on the Dwarf board 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.

If the issue persists even after the tension is correct, deviating towards higher or lower values might be necessary. Be sure to make the same adjustment on both sides.

Phase Stepping and crash detection

Once the Phase stepping is enabled, either by the menu or through the selftest, the crash detection is automatically disabled. At the moment, it is not possible to use both features at the same time. To disable Phase stepping and enable Crash detection, go into the printer menu to Settings -> Hardware -> Phase stepping, and set it to disabled. Then, go to the Settings menu to Crash Detection to activate it.

Same experience as @Hov3Dskou. Whining returned in a future print.  I don't recall if it was very next print or later. Firmware 6.0.0. After repeating phase step calibration it is now quiet on the current (very next) print. Power not switched off between calibration and current print.Edit: after a power down, it is now still silent. Not sure what caused the whining to return the first time, now good.

I ran the phase stepping calibration, the printer picked up tool #1 and everything went fine. As crash detection is more important for me at the moment, I went ahead and disabled phase stepping and enabled crash detection, then went ahead and parked the tool from the menu. The printer managed to crash the head and an error popped up. After resetting the printer I tried to park the head again and it made a _horrible_ noise but somehow managed to force the tool into the parking position.

Hmmm wierd..:When I do the Phase Stepping Calibration the printer turns completely silent. Then I print a model to enjoy the new silence, ...no problemBUT... If I then print the same model again, simply by selecting "Reprint", then the whining motor-noice is back again until I make a new calibration..?? It seems that the printer do not save the calibration..? Anybody else with the same behavior..?

Hello, which FW version do you have?
