1. Why do we need the auto level sensor on your 3d printer?
3D printing, the most important thing is the first layer, if the first layer can stick to hot bed well, the printing model can be successfully completed (if no accident). But the first layer is not so easy, one of the reasons is whether hot bed is the level or not. If hot bed is not level, it may lead to a problem, that the first layer of can be very strong in one position and not stick at all in the other position, or even damage nozzle (cause hot bed is not level, nozzle would be hit when moving from a low position to a high position).
