Hi, I'm new to 3D printing and recently I bought a Prusa i3 S-508. I've managed to assemble everything and get everything to work but the extruder fan cooler, and without that I can't print right because the filament gets melted inside the tube before the hot end. I've tried this to make the fan cooler work: first, within Repetier Host I can manual control the fan to turn it on with a button, but I press the button and nothing happens. Second, I edited my G-Code from the print and saw that there was a "M-107" command, and changed it to "M106 S255", saved the file and started printing, to my surprise, it didn't work. I thought it had to be hardware, so I checked the motherboard but the cable is connected in the right place, and the fan electric contacts seem to be fine too. Another thing I've noticed is that when I try to turn on the fan, a green light in the motherboard turns on. If anybody can help me to fix this I would be very grateful, because I don't really think the fan is damaged. Tell me if you need any photos. Thanks
