ZONESTAR 3D Printer Auto Leveling Sensor 3D Touch Bed Leveling Sensor


SKU: 32953075559 Categories: ,


3DTouch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of your print surface. It can greatly improve the printing precision of your 3D Printer.

3DTouch features simple, smart and precise. It could work with nearly any kind of bed materials, such as glasses, woods, metals and so on.

The main functions and controls of 3DTouch are the same as most auto bed leveling sensors, which consists of a RC servo and a micro switch, thus, 3DTouch can be used on almost every 3D printer control board.

By using progressively designed solenoid and hall sensor, 3DTouch can integrate high precision in such a simple structure. To make it more user-friendly and to bring you more enjoyable printing experience we add many smart functions such as self-test, false alarm, alarm release and test mode for M119.
