Red lights on control board

hello. I recieved my longmill and assembled to the point of powering up. In the step where power gets turned on and the red lights in the board should be on, only 3 sets are on. The fourth set is not lite up. What do I do?

Thanks

We usually reject boards which have defective lights, but it’s possible that it either got through or broke in transit. I would suggest moving forward with the assembly and then when you go to move the machine it’s possible that one of the motors may not move. It’s also possible that the light on the driver broke but the driver as a whole is still fully functional; in this case you’ll find that your LongMill still works as expected :slight_smile:

If you run into issues, let us know :+1:
