Hi!
After spending hours and hours going through the search results on the Googly thing, flashing the firmware and trying stuff out, I don't know what to do. I'm using a Fabrikator Mini bought from HobbyKing, and I'm trying to add a software controlled fan using the Reprap Ramps 1.4 RRD Fan Extender. Fabrikator Mini uses a MKS Base v1.3 board, although I've seen another Mini with a 1.4 board. Anyway. I've tried M42, M106, M107 and whatnot, but the fan is always on at full speed. According to the almighty interwebs, servo pins should consist of all digital pins (at least D2 and D4), but mine has D12, D11, A12 and A11. A pins are probably analog, so they can't provide PWM, and PWM is all I want.
What do I need to do to get it working? ::o
