Motherboard Precautions

Power Indicator​

Loading...
  • When powered only via TYPE-C without connecting other motherboard power, at least two LEDs should be lit: 3.3V and 5V
  • After connecting the motherboard power, the motherboard power LEDs should be lit: 3.3V, 5V, 12V
  • After connecting the driver power 0-2, driver power 3-7, and heated bed power, the power indicators on the lower left side of the motherboard will light up properly

Troubleshooting​

Notice
  • Without any external devices connected (drivers, endstops, 12864, etc.)
  • When powered only via TYPE-C, at least these two LEDs should remain lit: 3.3V and 5V

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

  • If the issue persists after replacing the jumper and Type-C power is confirmed to be supplied normally, please contact after-sales support

  • If one of 3.3V or 5V is blinking, it indicates a chip short circuit. Please contact after-sales support
