This has happened to me twice now: When printing a part at the maximum height of the print volume, everything prints fine. When the part finishes cooling, the print head moves to a corner and the print bed moves forward. However, since the print is so tall, the hotend tip hits the side of the part–damaging it or knocking it over.
Is this some error in the end g-code? It seems that when the prints finishes, the hotend lowers slightly below the maximum Z height. So when it finishes cooling, and moves to the corner, is has the chance to hit a maximum Z height part. How can I fix this?
