I had bought Bart's fix before I even got the extruder running, just from the experiences of others.

I usually use the Jet filament from Amazon, but they were out, so I bought one roll of PLA from another supplier. It is oval in shape, and averages 1.74 in the wider dimension, and all over the place, down to 1.70 in the smaller, so I am glad I have the fix.
I have no idea or recollection of how I got the gear onto my motor, but none of my looking found a size .050 allen wrench to take it off. I may have never really tightened it, just used my smallest 1.5mm to try to turn it down to the flat on the shaft. At any rate, couldn't get it off, and the plan to reverse the gear didn't happen, and the Bart's Fix modified extruder using the original, un-reversed gear still stopped feeding about 20% into the print. I am off to Home Depot to buy a correctly sized wrench, and get the gear off and reverse it. If that doesn't work, I am buying the MK7 that has been recommended.
