Mainboard Precautions

Power Indicator Lights

• Only through TYPE-C power supply and not connecting other mainboard power supplies, at least two lights 3.3V and 5V should be lit
• After connecting the mainboard power supply, the mainboard power indicator light should light up 3.3V, 5V, and 12V
• After connecting the drive power 0-2, drive power 3-7, and bed power, the power indicator light at the lower left of the mainboard will normally light up

Problem Solving

Notes

• In the absence of any external devices (drivers, limit switches, 12864, etc.)
• Only through TYPE-C power supply, at least two LEDs 3.3V and 5V should be constantly lit

• If 3.3V and 5V are not lit, check the mainboard 5V jumper
• After replacing the jumper, if it is still the same, and confirming that the typec is normally powered, please contact customer service
• If one of 3.3V, 5V, and 12V is flashing, it indicates a chip short circuit, and you need to contact customer service
  

Driver

• Please note the driver power supply, the driver power supply has two channels, the first channel supplies power to the driver 3-7, and the second channel supplies power to 0-2
• The mainboard supports an external driver Wiring and Configuration Tutorial

Limit Switch Ports

• Except for the last drive port (Drive7) which has a limit switch jumper, the other drive ports have no limit switch directly connected to the limit switch port
• If you find that the limit switch port is not working, you can replace the limit switch port or cut off the no-limit switch pin of the driver
