Auto Bed Leveling causes Rod to pop out

Hi Guys,
Last time I messed with this, it would get five minutes through the initial stages and then a rod would pop out because it would go out too far.
It would still mange to continue for some reason with 5 rods but obviously there is a problem so I canceled the procedure.

Can anyone guide me how to fix this so Auto bed leveling so it works. I am in bad need to get this feature working as most of problems I'm experiencing are deriving from the bed not being level.

Using RichCartel firmware on a Cherry PI printer.

Soon there will be better Delta Auto Bed Leveling code. But it will be another 5 or 6 weeks until it is ready.

For Delta Printers you control this with DELTA_PRINTABLE_RADIUS and DELTA_PROBEABLE_RADIUS. For Cartesian printers, it is controlled by this: (Please ignore the fact this is using Delta numbers)

// Travel limits after homing (units are in mm)
#define X_MIN_POS (-DELTA_PRINTABLE_RADIUS)
#define Y_MIN_POS (-DELTA_PRINTABLE_RADIUS)
#define Z_MIN_POS 0
#define X_MAX_POS DELTA_PRINTABLE_RADIUS
#define Y_MAX_POS DELTA_PRINTABLE_RADIUS
#define Z_MAX_POS MANUAL_Z_HOME_POS


#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)
