I was trying to do a 2 color print and printed the first 8mm in one color and used the Stop printing at height to stop the print,
then I changed the color in my printer and selected Start printing at height 8mm.
In the initialization code, it moved the bed up to the limit switch and then when it moved the head across the bed to the front left corner to pre-extrude the plastic it hit the existing print as it moved diagonally across the bed.
Suggest moving the platform down more than the 8mm offset before moving.
