I need to upgrade to RC7... I've been on RC6 since release and, aside from stupid things I've done, I've never had a failed print since. Probably 80+ prints and 0 failures with mesh bed leveling setup (well, zero height/bed leveling issues, I've goofed up plenty of stuff). So again, big thanks for your work on this. I need to get the Ultimaker 2 clone I'm building done and move over to RC7.
