- Stepper Motors: Connect your Nema17 or Nema23 stepper motors to the X-MOTOR, Y-MOTOR, and Z-MOTOR ports. Ensure correct polarity.
- Spindle Motor: Connect your 24VDC spindle motor to the SPINDLE port. This port supports PWM speed control (0%-100%).
- Laser Module: If using a laser, connect it to the 3-pin PWM/TTL signal control module port. Ensure the laser is 12V 5Amax.
- Limit Switches: Connect X, Y, and Z limit switches to their respective ports (X-limit, Y-limit, Z-limit).
- Probe: Connect your probe to the designated probe port.
- Emergency Stop: Connect a 2-pin emergency stop button to the emergency stop port.
- Power Button: Connect the power button switch to its dedicated port.
3.2 Offline Controller Connection
Connect the offline controller to the control board using the provided ribbon cable. The offline controller allows for direct control without a computer.
