Problem Solving

Notice

• In the absence of any external devices (driver, limit switch, 12864, etc.)
• Only through TYPE-C power supply, at least two LEDs 3.3V and 5V will be always on

• If 3.3V and 5V are not lit, check the mainboard 5V jumper

• After replacing the jumper, it is still the same, and confirm that the typec is normally powered, please contact customer service

• If one of 3.3V and 5V is flashing, it means there is a chip short circuit, please contact customer service

  

Driver

• The driver power supply can use 48V but all drivers must use 48V
• The mainboard supports external drivers Wiring and Configuration Tutorial

Limit Switch Port

• If the limit switch port is not working, you can replace the limit switch port or cut off the unlimited port of the driver
  

Firmware Burning

• The mainboard uses an SD card for burning
• Previously, due to tutorial issues, DFU was used for burning. If you need to update the firmware, please re-flash BL
