Motherboard Precautions

Power Indicator Lights​

Loading...
  • When powered only via TYPE-C without connecting other motherboard power sources, at least two lights, 3.3V and 5V, should be lit.
  • After connecting the motherboard power supply, the motherboard power indicator lights should show 3.3V, 5V, and 12V.
  • The power indicator lights at the bottom left of the motherboard will only light up normally after connecting the driver power supplies 0-2, driver power supplies 3-7, and the heated bed power supply.

Troubleshooting​

Important Notes
  • With no external devices connected (drivers, limit switches, 12864 display, etc.)
  • When powered only via TYPE-C, at least the 3.3V and 5V LEDs should remain steadily lit.
  • If 3.3V and 5V are not lit, please check the motherboard's 5V jumper.
  • If the issue persists after replacing the jumper and confirming the Type-C power supply is functioning normally, contact customer service for after-sales support.
  • If either the 3.3V or 5V light is blinking, it indicates a short circuit in a chip. Contact customer service for after-sales support.

Drivers​

  • Driver power supply can use 48V, but all drivers must use 48V simultaneously.
  • The motherboard supports external drivers. Wiring and Configuration Tutorial

Limit Switch Ports​

  • If a limit switch port is found to be non-functional, you can switch to another limit switch port or cut the no-limit pin on the driver.

Firmware Flashing​

  • The motherboard uses a TF card for firmware flashing.
  • Previously, due to tutorial issues, DFU was used for flashing. If you need to update the firmware, you must reflash the BL.
