X1C Homing Tool noise during preparing to print

Bambu Lab X Series X Series Firmware Public Beta

I recently upgraded to 01.11.02.00 + AMS1 00.00.06.75 from a much older version. After doing this I ran a full print calibration (twice). ie. The 4 stages, Micro LIDAR Calibration thru Auto Bed leveling.

I made a small cube 10x10x5mm. When I start the print I see

2:49 Cleaning nozzle tip, 3:20 Bed touches nozzle, 4:08 Bed touches nozzle at the center of the bed, 4:51 Homing tool, 5:04 The printers steppers make a rising buzzing sound, a pause, then again (this time a softer buzzing sound) 5:35 prints a long trace at the front of the bed, 6:00 Starts printing cube.

The estimated print time 9:26 actual print time 9:30

My question is about 5:04 the buzzing sound. It sounds a bit like when the printer is calibrating on step2, Motor noise cancellation. On the older firmware this never happened. I assume that its normal. Can someone tell me why it does this, what is the purpose? Its slightly annoying.

Yes, that’s calibrating for vibration compensation. No, you shouldn’t disable it, but if you really want worse prints, here’s how:

@CarbonForge Hi thanks for the info. I read the help section about removing this function and see that it’s used to check the belt tensions etc. as you mentioned, it’s recommended to not disable it. So I will just get used to it now I know what it’s for.
