Motherboard Precautions

Power Indicator Lights

When powered only via TYPE-C without connecting other motherboard power sources, at least two lights, 3.3V and 5V, should be lit.
After connecting the motherboard power supply, the motherboard power indicator lights should show 3.3V, 5V, and 12V.
The power indicator lights at the bottom left of the motherboard will only light up normally after connecting the driver power supplies 0-2, driver power supplies 3-7, and the heated bed power supply.

Important Notes

With no external devices connected (drivers, limit switches, 12864 display, etc.)
When powered only via TYPE-C, at least the 3.3V and 5V LEDs should be steadily lit.

If the 3.3V and 5V lights are not lit, please check the motherboard's 5V jumper.
If the issue persists after replacing the jumper and you have confirmed the Type-C power supply is functioning normally, please contact customer service for after-sales support.
If any of the 3.3V, 5V, or 12V lights are blinking, it indicates a chip short circuit. Please contact customer service for after-sales support.

Please note the driver power supply. The driver power is divided into two circuits: the first supplies power to drivers 3-7, and the second supplies power to drivers 0-2.
The motherboard supports external drivers. Wiring and Configuration Tutorial

Except for the last driver port (Drive7), which has a no-limit jumper, the no-limit function for other driver ports is directly connected to the limit switch ports.
If a limit switch port is found to be unusable, you can replace the limit switch port or cut off the no-limit pin of the driver.
