If the Mini Delta is trying to home in the wrong direction then you may need to invert the XYZ motor direction
M562 E ;Inverts Extruder/Feeder Mechanism motor direction M500 ;Saves changes to EEPROM Reboot printer to complete the process (turn off, then on)
M562 XYZ ;Inverts X, Y, and Z motor direction M500 ;Saves changes to EEPROM Reboot printer to complete the process (turn off, then on)
