This is the AB1 breakout module for one stepper control Axis from the F46 controller. The stepper control signals (STP, DIR, EN) are then connected to an external stepper driver.

Connections:

1. RJ45 to F46’s AXIS port (XYZABC)
2. Screw terminals for P and N Limit switches, with 5V power for active switches.
3. Screw terminals for Home switch, with 5V power for active switches.
4. Screw terminals for stepper control signals: STP, DIR, EN, and GROUND.
5. Jumper for connecting the RJ45 Shield to Ground.
