TAZ PRO FIX Stripping and Clogging Problems

For $25 in parts, the TAZ PRO can be everything you hoped it could be!

After 250+ (Edit: I just looked it was only 60) failed prints and countless hours removing stripped or clogged filament and searching for answers, I was giving up hope that I would ever see this thing finish a print. While searching the Lulzbot forum I found a user post that I cannot re-find to post on or give him/her credit, but he/she suggested that all his/her problems were thought to be “Heat Creep” and he/she was 100% correct. I tried everything different filament, settings, etc thinking there was no way that could be the problem with this amazing “Looking” printer, I was wrong. After Ty-rap-ing a computer case fan to the side of my print head I got my first successful print! (short prints like the test print and calibration always seemed to work as long as the printer was off for a while (#1 clue that heat creep was a problem))

I quickly designed and installed a new cooling fan setup for the Lulzbot Pro and it not only looks amazing but it prints that way too! See the attached files for the fix.
