Hi everyone, I just bought my first 3D printer and it's awesome. It's a PowerSpec 3D Pro dual extruder from Microcenter. I'm using ReplicatorG for printing and Skeinforge for slicing/gcode generation.

Having said that, I'm having some challenges printing with PLA filament. Take a look at the photos below to see what I'm talking about. This is all from a single print job, but it's pretty consistent with what I've been getting. I've adjusted print bed temp (anywhere from 50 - 75 C), hot end temp (from 165 - 185 deg), feed rate (from 33 - 60 mm/s), all without being able to get a clean print from top to bottom. I get the curling corners regardless of what my print settings are, with a raft or without.

Oh yeah, I'm printing on the Kapton tape that came with the printer.

I'm actually going back and leveling my print bed again just to cross that off the list. Thanks for your help!
