    while we tried to get the y -axis working, the fans cooling the extruder caught our attention. Shouldn´t they blow air through the heat stop cooling ribs of the extruder? We got them working in reverse sucking the air out of the ribs blowing towards the right extruder/ right case wall.

    Maybe theres something smart behind that but logically I would reverse them.

    Help would be appreciated.


    Generally the way they are setup is correct. If you blow air through the heatsink you get a form of backdraft from the fan on the outside of the casing.
