Hi, All,
John Lindo has found that he has better control of his 3D prints when he controls not only the part cooling fan, but also the fan that cools the extruder.? (I am not sure why the extruder needs to be cooled, but...)? My printer does not have independent controls for the fans, so I designed and made a simple, 555-based, PWM control for these three fans.? I just managed to print the housing for it yesterday, and haven't assembled it yet.? I thought some photos might be of interest.
