Why my 3D printing module is clogged?

1. The vertical side fan isn't working.

The side fan is designed to work and cool off the heatsink once it's power on. If not, it will cause the nozzle clog problem.

If you meet this problem, please email [e-mail] to describe the problem and we will send you a replacement fan part as soon as possible.

Or you can order a fan in the local store and replace it. The spec of the fan is:

• Size: 30x30x10 mm

• Power: 12V 0.1A
