Cupcake+ABS+HBP(125)+MK5(225) wade style stepper.

I'm very happy with my prints, but I want better! Seems as if my thread width gets thinner over the coarse of a build. It is probably heat related. I've tried actively cooling my stepper or my drive tube, or at the filament drive gear. Maybe it's a combination of all three. I dunno. I was wondering if others have insight on the issue.
