The extruder is equipped with two fans – upper and lower. The main role of the

extruder upper fan is to cool down the extruder, whereas the extruder lower fan

cools down each layer of the print. Therefore, if your model warps, melts, or you

can notice burn marks on its surface, you should check the extruder fans for

proper operation. The following manual presents how to replace both extruder

fans.

The following manual shows the M200 repair work. For the M300, these procedures are

the same.
