Is it possible to setup a M4 board for a delta printer? I looked at the pin map in the git and see end stops for X. Y and Z but did not see a pin for the bltouch.
But for a Delta I need something like
#define X_MAX_PIN 4
#define Y_MAX_PIN 35
#define Z_MAX_PIN 21
#define Z_MIN_PIN ??? //touch sensor for leveling
The M4 support BLTOUCH also there is connector for that
you can use any other unused pins like 13,15. except the pins higher than 100 which are expanded pins can only be used as output.
