Topic: New bed level probe idea
Marlin now has the ability to take readings from a probe over the area of the bed and then adjust the Z axis on the fly to compensate for out of level or warped beds. Most probes use a pin that has to be extended and retracted, but here is a demonstration of using the hot end by itself as a bed probe. The hot end mount is hinged on one side so when it gets pressed against the bed it moves up slightly and triggers a switch.
