Can't print large objects. Printer won't touch left side
Repetier firmware (or host) is cutting the entire left side off large objects. There is about a 2 inch strip down the left hand side of the print bed the extruder wont touch and just draws everything that cross the line, down that line.
If it's drawing that is clipped your xmin is set wrong. If you can not move by sending gcodes to that coords directly it is firmware. Please do not use manual move buttons for this as they limit it to what host thinks is the limit and not what firmware really thinks.
