Ok, so I finally got my Prusa i3 Rework up and running, but I'm having some issues with my prints. It seems to be scorching the PLA on one side, and there's also some kind of drift or lean happening:

The scorching:



The lean:



I've got a Jhead, .3mm nozzle, 1.75mm filament. I've tried a bunch of settings, but this last one was printing at 185 deg, 60 deg hot bed, 25% fill (honeycomb). I obviously don't want to try printing anything bigger until I figure this out.

Thanks!
