Firmware upgrade/downgrade vs manual bed calibration


is it necessary to level the bed manually after each firmware upgrade/downgrade and align nozzle? Or these settings are being stored somehow out of the firmware?

Which machine? On M200, if I remember correctly, the bed calibration remains. However, there have been changes in the calibration algorithm between firmwares, so I always ran bed leveling anyway.

M300 Dual. Manual calibration of the glass bed is a little bit time consuming thus my question :wink:
