Motherboard Precautions

Power Indicator Light​

  • When powered only by TYPE-C without connecting to other motherboard power supplies, at least two lights 3.3V and 5V should be on
  • After connecting to the motherboard power supply, the motherboard power lights should be on 3.3V, 5V, VCC

Problem Troubleshooting​

Notice
  • Under no external device conditions (drivers, limit switches, 12864, etc.)
  • Only powered by TYPE-C, at least 3.3V and 5V two LEDs will be constantly on
  • If no lights are on, it indicates a short circuit and you need to contact customer service after-sales
  • If one of the 3.3V, 5V lights is flashing, it indicates a short circuit and you need to contact customer service after-sales

Drivers​

  • The motherboard supports external drivers Wiring and Configuration Tutorial

Limit Switch Ports​

  • Please pay attention to the wiring order, three-wire limit switches need to be careful with 5V, GND, S these three if connected wrong may cause motherboard damage
  • If two wires are directly connected to S and GND it is fine
  • PL08 and other proximity switches need to connect a diode outside the signal port to reduce the voltage to below 3.3V

Firmware​

  • Due to button issues tutorial update using Katapult firmware for firmware burning
  • It is recommended to use a computer to flash the Katapult firmware and then burn klipper through the Katapult firmware
  • BL Burning
