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
and5V
. - After connecting to motherboard power, the motherboard power light should illuminate
3.3V
,5V
, and12V
. - 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
and5V
.
- If
3.3V
and5V
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
, or12V
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.
