using an SKR mini v3 and its great with builder except one flaw is the fan PWM cannot be set to soft in builder  
so now im either having noisy 5015s and a working bltouch or no bltouch which is the only way i can home and quiet fans.

i’ve tried compiling the firmware manually but so far its refusing to use bltouch

I’m facing same issue. It would be great to include hardware PWM settings and/or software ones.
