Mainboard Precautions

Power Indicator

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

Troubleshooting

Notice
  • In the absence of any external devices (drivers, limit switches, 12864, etc.)
  • When powered only through TYPE-C, at least two LEDs should remain constantly lit: 3.3V and 5V.
  • If 3.3V and 5V do not light up, check the motherboard's 5V jumper.
  • If the issue persists after replacing the jumper and confirming that TYPE-C is providing normal power, contact customer service for assistance.
  • If one of the lights 3.3V, 5V, or 12V is blinking, it indicates a short circuit in a chip, and you should contact customer service for assistance.

Drivers

  • Please note that the driver power is divided into two circuits: the first circuit powers drivers 3-7, and the second circuit powers drivers 0-2.
  • The motherboard supports external drivers Wiring and Configuration Guide

Limit Switch Ports

  • Except for the last driver port (Drive7) which has an infinite limit switch jumper, all other driver ports have the infinite limit switch directly connected to the limit switch port.
  • If the limit switch port is found to be non-functional, consider replacing the limit switch port or trimming the infinite limit switch foot from the driver.
