R3 Upgrade, Print Fan no longer works
Prusa,
I was printing away today when I had a filament jam. Thought that I would upgrade to the R3 parts that I printed last week while i had it apart.
After reassembling everything, my Print Fan no longer works and my Wizard fails.
The fan was never disassembled, I simply removed the 5 Zip-Ties from the back of the carriage and unwound about 5 wraps of the Spiral Wrap to allow room to move the components around. The sticker on the back of the fan is partially removed and the connections inside look fine. No wires were cut or show any signs of damage. I've checked inside the Electronics box and everything in there is properly connected.
I've had the printer since March and have no other major issues with it.
HELP!
Any assistance or ideas gratefully accepted.
Thanks,
Lane

Mods,
Please move this discussion over to the I3 Mk3 forum where it belongs, I placed it here by mistake.
Thanks,

Lane, maybe you habe a broken cable ? The zipties are very strong, please doblecheck. Noddle on the cable, maybe it works.

I think you made the same mistake as I did.
When I assembled the extruder, I accidentally clamped one of the fan cable conductors. I soldered the cable and everything worked again 🙂

I did the same thing, i pinched the print fan wires when tightening the two extruder printed parts together and also had to repair the wires.
