Re: Marlin homing problem

thats just wrong.... and backwards

If you home to max then tell the printer its now at 0... no idea what that would do... break thing I would guess

also the next line is
#define X_MAX_LENGTH (X_MAX_POS - X_MIN_POS)
#define Y_MAX_LENGTH (Y_MAX_POS - Y_MIN_POS)
#define Z_MAX_LENGTH (Z_MAX_POS - Z_MIN_POS)

so your printer is X -250 by Y -210, Z -180, which is just silly...

try the defaults.
#define X_MIN_POS 0
#define X_MAX_POS 205 // important to get this correct, as it will move this far left to get to 0
#define Y_MIN_POS 0
#define Y_MAX_POS 205
#define Z_MIN_POS 0
#define Z_MAX_POS 180
