I revisited Roberto's suggestion and ended up with some very solid prints. The outer surface is a little rough but the wall widths came out nice and consistent. In almost a year I have only had one print failure due to a clog. This weekend I had 6 failures 4 of them were spool issues and two were power failures from the snow storm. Turns out at least 2 were due to a bit of plastic flashing on the inside of the spool that was catching the filament. I was afraid it was my altered profile but the last three prints are near perfect.
