Motherboard Precautions

Power Indicator

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

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 be 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 it is confirmed that the Type-C is providing power normally, contact customer service for after-sales support.
• If either the 3.3V or 5V light is blinking, it indicates a chip short circuit. Contact customer service for after-sales support.
  

Drivers

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

Limit Switch Ports

• If a limit switch port is found to be unusable, you can replace the port or cut the driver's no-limit pin.
  

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 need to reflash the BL.
