Z axis won't go up
So far I don't have much to complain about with the 6, but I've only had it 3 days and only a handful of prints through it. I have noticed that if the bed goes too far to the bottom, I can't get it back up to home position. It's like there needs to be a limit switch at the bottom to ensure it doesn't go too far. Once down there I need to hit home and then try to manually twist the screw till it seems to re-engage and then it will go up. Am I missing something?
