The "Home" command is supposed to put the head exactly over the front left corner of the bed right? I've been printing successfully for a few days now, but I am trying to print some larger prints now and they are shifted off the bed in the back and over too far to the left. So I got to thinking and realized it's either because my bed is over to the right and back to far, or my print head is over to the left and not far enough up front. My head goes home and it's a good cm to the left of the edge of my print bed and back a good cm from the front of the board as well. Which do I move, the print head or the bed and how?
