    Hello Everyone,

    Does the rear fan run at all. When I'm printing the only fan running is the extruder. I've never seen the fan come on. Any help would be appreciated.

    Thanks

    Bob

    The parts cooling fan (the one aimed at the part you are printing) only runs as needed. This is controlled by slicer settings.
    The Fan underneath on top of the RAMPS board runs all the time.
    The fan on the hotend run all the time the hotend is heated.

    If you are printing ABS then this is likely the case. You don't want it on for that.
