Hey, How do I use the OPT fan circuits on the Felix 3.0 board to power a 12v extruder fan?
Thanks
12v Fan for hot end..

Not sure if I understand the question. Just connect it to OPT instead of MAIN (like shown in the assembly manual for the dual extruder).

I have it hooked up to the opt output. Doesn’t seem to be any voltage
Provided the fan is working, and I guess it does, the problem is probably a faulty output transistor. See also http://www.felixprinters.com/forum/view ... =11&t=1652.Bobbystone wrote:I have it hooked up to the opt output. Doesn’t seem to be any voltage
