Cold Pulls

I finally have good prints happening again.

I picked up cleaning filament and printed about a foot of that. After some cold pulls with the cleaning filament, I’m doing cold pulls after every print.

I found I can still get a garbage print with PETG if I print a test batarang and immediately print something else without doing a cold pull.

This last print is looking perfect. (11 hours into a 33 hour print)
