Due to the needs of the actual project, I only connected a stepper motor on grb. #define HOMING_CYCLE_0 (1<<Z_AXIS) // REQUIRED: First move Z to clear workspace. If they're both driven by the same driver, as normal because GRBL only controls 3 drivers, then the easy but noisy way is to arrange the endstop switches such that the home position is only registered once both are tripped. Liberal use of Z offset and a custom focus macro that cheats up a few mm (I go up 3. i want 0,0 to be the front left corner so I always work in positive coordinates. You can have more than one axis home per cycle. Typically a Z would home up first to clear the work before you home in X and Y. I believe these should be negative with machine zero being back right.
