I kinda got what you meant. I tried using the following parameters and not It is not making noise anymore and works properly.
M915 X Y S5 R1 F1 H2 ; set sensorless homing
Do I need to put the same M915 at the end of my config.g after the endstop section? (instead of M915 X Y R0 F0)
Also, using a Biqu microprobe as Z sensor - Should I use the same parameters for Z axes such as D3 for stealthchop? Does my homez looks good:
; homez.g
; called to home the Z axis
