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 will be constantly lit

• If 3.3V and 5V are not lit, check the mainboard 5V jumper
• After replacing the jumper, it is still the same, and confirm that the typec is normally powered, contact customer service for after-sales
• If one of the lights 3.3V, 5V and 12V flashes, it indicates a chip short circuit, contact customer service for after-sales
  

Driver

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

Limit Switch Port

• Except for the last drive port (Drive7) which has a limit switch jumper, the rest of the drive ports have no limit switch connected directly 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 drive
  

Firmware Burning

• The mainboard uses an SD card for burning
• Previously, due to tutorial issues, DFU was used for burning. If you need to update the firmware, please re-flash BL

Thermistor

• The mainboard thermistor port supports
  • NTC thermistor
  • PT1000 thermistor
