Mainboard Notes

Power Indicator Light

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

Problem Solving

Note

• Without any external devices (driver, limit switch, 12864, etc.)
• Only through TYPE-C power supply, at least two LEDs 3.3V and 5V will 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 confirm that typec is normal power supply, please contact customer service

• If one of 3.3V, 5V, and 12V is flashing, it means there is a chip short circuit, please contact customer service

  

Driver

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

Limit Switch Port

• Except for the last driver port (Drive7) which has a limit switch jumper, the other driver 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
  

Firmware Burning

• The mainboard uses a TF card for burning
• Previously, due to tutorial issues, DFU was used for burning. If you need to update the firmware, please reburn BL
