Where do you guys buy ABS filament from?
I bought some ebayy cheapo filament it it is not working out. It leaves gaps between layers because after retraction it takes a second or so to extrude again, i think it is very viscous. I bumped the extruder temp to 255c, no luck.I played around with the retraction setting, went all the way down to 1mm at 30 mm/s retraction, and this made the gaps less frequent. I ended up turning retraction off and it eliminated the gaps between layers.
