This may not actually be much of a problem. I guess I just need some advice. I received my R2 today and set everything up. It printed a perfect test print, but I had a hard time getting the part (and raft) off the print bed. When I use the included putty knife, it scratches the bed surface pretty bad. Is this a problem? If so, is there any way to avoid this? Also, you know how the extruder does a single line pass along one side of the print bed before it starts printing the part? I could not get some of the plastic it laid down on that line, even when I used an x-acto knife. Patrick p.s. I am just using the included spool of PLA for these prints right now.
