Currently have Ramps 1.4, Marlin and slic3r. The question is how to control the speed of the carriage blowing air on to the printed parts using PWM. Slic3r does give this option to control fans. Here is the big BUT I cannot figure out. What pins on the Ramps I should use to control the fans or how I config them in Marlin apart from accessing Pins.h to work with slic3r. I have the option of either 12v or 5V fans.
It can be done as many user's use PWM to control cooling when printing especially when doing Bridges and corners.
Cheers for any help
