Even w/ the BL touch you'll need to level the bed (the official term is "tramming") occasionally bc the BL-T can only account for so much. E.g. its still possible for the mesh to get out of usable bounds.
Plus keep in mind auto bed leveling only makes the bottom of the part stick - it down't actually make the part flat or level. It just makes it an inverse of the ame contour as the bed. Its just so small you can't really see it.
Imagine you needed a perfect 100cm cube and the bed was out of level. Its exaggerated but what you would end up with is a cube that has 1 side 100.1 cm tall and another 99.9 cm tall, and the top and bottom faces are not parallel to one another.
BTW [USER=92]@Tacoma747[/USER] same principle still exists w/ that X1C too. You DO have to manually level the bed occasionally.
