X axis homing in + direction about sprinter HOT 4 CLOSED

Hi Bryang

If X_HOME_DIR is change to 1 (MAX ENDSTOP) you have to change the pins.h to use the right variable / input
this to lines
#define X_MIN_PIN 18
#define X_MAX_PIN -2
to
#define X_MIN_PIN -1
#define X_MAX_PIN 18

Hi

Thank you. I actually realised that it was the Y axis that was mirrored but have applied the same principle to get that to work with the + homing.

I am used to working in C and there I would normally include something like:

#if X_HOME_DIR == 1
. #define X_MIN_PIN -1
. #define X_MAX_PIN 18
#else
. #define X_MIN_PIN 18
. #define X_MAX_PIN -2
#endif

Can we do the same thing in Arduino. Knowing that I am an idiot I always try to 'idiot proof' any settings that a user has to mess with.

Thanks

Hi

This would be a way but there some printers that use MIN and MAX Endstops.
For this printers this code will not work.

It's not easy to get a firmware for all boards and Printers

Multi-compatlibility is always a pain.

Thanks for the help, all is working correctly now.
