Mainboard Precautions

Power Indicator​

  • When powered only through TYPE-C without connecting to other motherboard power, at least two lights should be on: 3.3V and 5V.
  • After connecting to motherboard power, the motherboard power light should show 3.3V, 5V, and 12V.
  • After connecting drive power 0-2, drive power 3-7, and hotbed power, the power indicator light on the bottom left of the motherboard will light up normally.

Troubleshooting​

Note
  • In the absence of any external devices (drivers, limit switches, 12864, etc.)
  • When powered only through TYPE-C, at least two LEDs should remain constantly lit: 3.3V and 5V.

  • If 3.3V and 5V do not light up, check the motherboard's 5V jumper.

  • If the issue persists after changing the jumper and confirming that the TYPE-C is supplying power normally, contact customer service.

  • If one of the 3.3V, 5V, or 12V lights is blinking, it indicates a short circuit in a chip; contact customer service.

Drivers​

  • Pay attention to the driver power supply, which is divided into two circuits: the first circuit powers drivers 3-7, and the second circuit powers drivers 0-2.
  • The motherboard supports external drivers Wiring and Configuration Guide

Limit Switch Ports​

  • Except for the last driver port (Drive7), which has an infinite limit switch jumper, all other driver ports have their infinite limit switch directly connected to the limit switch port.
  • If the limit switch port cannot be used, replace the limit switch port or cut off the infinite limit switch pin from the driver.

Firmware Burning​

  • The motherboard uses an SD card for firmware burning.
  • Due to previous tutorial issues, DFU was used for burning. If you need to update the firmware, you need to re-burn the BL
