Main Board Precautions

Power Indicator

Loading...

• When powered only via TYPE-C without connecting other main board power, at least two lights (3.3V and 5V) should be on
• After connecting the main board power, the main board power indicators should light up 3.3V, 5V, and 12V
• The power indicator on the lower left of the main board will only light up normally after connecting driver power 0-2, driver power 3-7, and heated bed power

Troubleshooting

Note

• In the absence of any external devices (drivers, endstops, 12864, etc.)
• When powered only via TYPE-C, at least the 3.3V and 5V LEDs should be constantly lit

• If 3.3V and 5V are not lit, check the main board 5V jumper
• If the issue persists after changing the jumper and TYPE-C power is confirmed to be normal, please contact customer service for after-sales support
• If one of the 3.3V, 5V, or 12V lights is flashing, it indicates a chip short circuit; please contact customer service for after-sales support

Driver

• Pay attention to the driver power. Driver power is divided into two circuits: one supplies power to drivers 3-7, and the other supplies drivers 0-2
• The main board supports external drivers Wiring and Configuration Tutorial

Endstop Port

• Except for the last driver port (Drive7), which has an infinite endstop jumper, the infinite endstops of other driver ports are directly connected to the endstop ports
• If the endstop port does not work, you can replace the endstop port or cut off the infinite endstop pin of the driver
