Main Board Precautions

Power Indicator

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

Troubleshooting

Notice

• With no external devices connected (drivers, limit switches, 12864, etc.)
• At least two LEDs, 3.3V and 5V, should remain constantly on when powered only through TYPE-C.

• If 3.3V and 5V do not light up, please check the motherboard's 5V jumper.
• If the issue persists after changing the jumper and confirming that the TYPE-C is supplying power correctly, contact customer service.
• If one of the lights 3.3V, 5V, or 12V is blinking, it indicates a chip short circuit, and you need to contact customer service.
  

Drivers

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

Limit Switches

• Except for the last driver port (Drive7), which has an infinite limit switch, all other driver ports have infinite limits directly connected to the limit switch.
• If the limit switch does not work, you can replace the limit switch or cut off the infinite limit pin of the driver.
  

Firmware Burning

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