Mainboard Precautions

Power Indicator​

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

Troubleshooting​

Notice
  • In the case of no external devices (drivers, limit switches, 12864, etc.)
  • When powered only through TYPE-C, at least two LEDs 3.3V and 5V should be constantly on.
  • If 3.3V and 5V are not lit, check the mainboard's 5V jumper.
  • If the issue persists after changing the jumper and confirming that TYPE-C is providing normal power, contact customer service for after-sales support.
  • If one of the 3.3V or 5V lights is flashing, it indicates a short circuit in a chip, and you need to contact customer service for after-sales support.

Drivers​

  • The driver power can use 48V but must use 48V for all drivers.
  • The mainboard supports external drivers Wiring and Configuration Guide

  • If the limit switch port cannot be used, you can replace the limit switch port or cut off the driver's limit switch pin.

Firmware Burning​

  • The mainboard uses a TF card for firmware burning.
  • Due to tutorial issues, DFU was previously used for burning. If you need to update the firmware, you need to reburn the BL
