There is a discussion on this top here. It seems like it’s an inductive sensor and it only has a very small detection range which makes it fairly useless for use on a glass bed. It’s a shame as there is very little to beat the flatness of a piece of glass and though Marlin software bed levelling is good it’s no replacement for a flat bed. > [@A350 - printing on glass](https://forum.snapmaker.com/t/a350-printing-on-glass/5238): > > does somebody have experience with replacing the original printbed with a glassbed? I would like to use the autolevel function for the initial leveling. The first print (I leveled manually before) didn’t work. Snapmaker did a autolevelling and on the first point the printhead pushed the glassbed down and I had to do an emergency stop. It seems like the manual leveling was gone and the machine tried to perform an automatic leveling which obviously went into the wrong direction.
