Just upgraded Marlin to new RC (to try to fix auto bed leveling problem). Z steppers work fine during normal movement, but immediately stop and whine continuously during Z home operation. Only other thing I changed was a proximity sensor in place of Z min endstop. Any suggestions greatly appreciated.

In your configuration.h file, change the homing feed rates to

#define HOMING_FEEDRATE {50*60, 50*60, 150, 0} // set the homing speeds (mm/min)


Folger Tech 2020 i3 and FT-5 as well as modified JGAurora A5 with direct drive E3D/Titan. All running the BLTOUCH.
Great kits. Having fun and running the heck out of them.
Running Marlin 1.1.0 RC8 on the i3 and FT5. Custom firmware on A5.
