Oh yeah, I definitely want to move up to a stepper upgrade.. Just can't drop the ~$200 on it right now. :(
But I did a few tests with different cool settings, and here's what I've got: (starting from the left)
The 1 seems to be the highest quality.. It has the greatest amount of smooth surface area, and is imperfect only with a small bulge from the surf
ace of one side of the tip. 2 is more blob-y than 1. The 10 has good shape but the entire tip area is rough. The 20 fell over while printing but is extremely rough over the whole surface.
