Geeetech

Thanks William, Checking the G-code from Slic3R, I can see the M106 - time to play

I have been using Cura slicer for my Geeetech Prusia I3 Pro B. In setting up Cura, as they don't have this machine specifically mentioned, I just selected "Prusa I3". It seems to work O.K., but the Print Cooling Fan options does not seem to do anything. Any suggestions?
