Weird Motor Sound at Homing with 3 Z-Motors with 1 driver every motor #108

it works, but on z homing the motors make a weird and loud sound.

https://www.youtube.com/watch?v=t8_eU9_tqEI the first 10 seconds its normally z moving, then z homing, you can hear the different

I use klipper v0.12.0-125

i used 3 z axis motors.

with my CR touch everything is fine only changing to BDSensor makes a weird sound at homing in Z, but not on normal moving.

i used 3 z axis motors with one driver every motor

I think it's a problem because while the Z axis is moving, the sensor is always measuring, but it's really very loud.

this happens in some multi z axis printers, the MCU control the multi z axis driver but at same time need to read the bdsensor at very high frequency. there are 2 solutions: 1: connect the BDsensor to the different controller, e.g. raspberryPi GPIO or the CAN module. 2: upgrade the firmware of BDsensor to the latest version that will let the bdsensor works as a switch sensor while homing. V1.2c

what's your bdsensor firmware version? you can check the firmware of BDsensor by M102 S-1
