Motherboard Precautions

Power Indicator Light​

Loading...
  • When powered only via TYPE-C without connecting other motherboard power sources, at least two lights should be on: 3.3V and 5V
  • After connecting the motherboard power source, the motherboard power indicator lights should show 3.3V, 5V, and VCC

Troubleshooting​

Important Notes
  • In the absence of any external devices (drivers, endstops, 12864 display, etc.)
  • When powered only via TYPE-C, the 3.3V light should remain constantly on
  • If the 5V light does not illuminate after connecting the motherboard power source and driver power source, please contact after-sales support

Driver​

  • The motherboard supports external drivers Wiring and Configuration Tutorial

Endstop Ports​

  • Please pay attention to the wiring sequence. For three-wire endstops, be mindful of the 5V, GND, and S connections. Incorrect wiring may damage the motherboard
  • For two-wire endstops, simply connect S and GND
  • PL08 and other proximity switches require an external diode at the signal port to reduce the voltage below 3.3V
