Sensorless Homing
#define SENSORLESS_HOMING // enable sensorless homing
#define xx_STALL_SENSITIVITY 8 // sensitivity setting, TMC2209 range from 0 to
255, higher number results in more sensitive trigger threshold, sensitivity too high will
cause endpoint to trigger before gantry actually moves to the end, lower number results in
less sensitive trigger threshold, too low of sensitivity will cause endpoint to not trigger
and gantrying continue. Other drivers range from 63 to -64, lower numbers result in a
more sensitive trigger threshold.
#define IMPROVE_HOMING_RELIABILITY // can be used to set independent motor
current for homing moves(xx_CURRENT_HOME) to improve homing reliability.
