I lowered my temp on the extruder to about 365 - 375f. All was good, I was happy till about the 6th layer at 0.3mm. It quit extruding.

I tore out the nozzle and the teflon tube and found that the filament was all hosed up in the teflon tube. I cleared it out, put it back together and tried again after changing some settings in Slic3r. Well again, about the exact same spot it stopped extruding... I was cursing up a storm and trying not to wake the kids up.
pulled the PLA out and tossed in the glow in the dark ABS and made a gecko for my daughter to make me feel better...
This morning I started thinkin about the issue and thought, well just maybe the dang filament is too hot in the barrel. I lowerd the temp a bit more and no go, same issue. Thought about it a bit more again and thought, well maybe the barrel needs to be cooled a bit.
I opened up Inventor (used it like twice in my life) and started to design a 40mm fan holder to blow air onto the extruder.
I came up with this cheesy part.
Had to drill out the holes with a 1/8" bit to slip the 3mm bolts thru but not big deal.
Mounted it up, cranked the temperature back up just under what I print ABS at (about 400f) and let it rip.
Dang if a part didn't print!!! Just a little air is all it took. Here is the second print I did.
I am now trying to make adjustments to Slic3r as I am getting more ooze out than with the ABS. I think I about have it, once I do I will post screen shots.
If anyone wants the STL for this fan holder let me know and I will post it up.
