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 12V
• The power indicator light at the bottom left of the motherboard will only illuminate normally after the driver power 0-2, driver power 3-7, and heated bed power are connected

Troubleshooting

Note

• When no external devices are connected (drivers, endstops, 12864, etc.)
• Powered only via TYPE-C, at least the 3.3V and 5V LEDs should remain constantly on

• If 3.3V and 5V do not light up, please check the motherboard 5V jumper
• If the issue persists after changing the jumper and the Type-C power supply is confirmed to be normal, contact customer service for after-sales support
• If one of the 3.3V, 5V, or 12V lights is blinking, it indicates a chip short circuit, and customer service should be contacted for after-sales support

Driver

• Pay attention to the driver power supply. It is divided into two paths: the first supplies power to drivers 3-7, and the second to drivers 0-2
• The motherboard supports external drivers Wiring and Configuration Tutorial

Endstop Ports

• Except for the last driver port (Drive7), which has an endstop jumper, the other driver ports connect to the endstop ports directly
• If an endstop port is not functioning, you can replace the endstop port or cut off the endstop pin of the driver

Firmware Flashing

• The motherboard uses a TF card for flashing
• Previously, due to tutorial issues, DFU was used for flashing. If updating the firmware is needed, reflash the BL

Thermistor

• The motherboard thermistor ports support
  • NTC thermistors
  • PT1000 thermistors
