I'm going to be doing the same thing once I get to that point in the build. I also read the D9 can be used. Here is my question:
Is it possible to connect more than on fan to a ramps 1.4 board?
I'm planning on running PLA for the most part and want to keept the feeder tube cool so I want to put a fan there but I also want to put a fan on the other side with a custom air nozzle to cool the PLA after it's on the platform.
Any ideas?
