It is an open source based auto leveling sensor for 3D printers. Simple, smart, high precision.
It can work with any type of bedding materials, such as glass, wood, metal, etc.
By using Hall sensor and solenoid, for 3D Touch can integrate high precision into such a simple structure.
To make it easier to use and to bring you a more pleasant printing experience, we added many smart functions such as self-test, false alarm, alarm release, and test mode for M119.
