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

By using progressively designed solenoid and hall sensor,It 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.

Due to the lack of specifications, this is a 4 stars experience. The specs do not match original BLtouch sensor. Trianglelab does not provide height specifications. So you have to struggle a bit with this to get the height correct. Apart from that, the sensor works great! I am using this on my upgraded Ender 3 pro with BTT v2.0 board. Using microswitch for homing and BLtouch for bed leveling only.

Comes in a plastic box, so it is protected during shipping. Takes some effort and research to get it working. You need to print the mount yourself.

It went long enough to the point of issue... Stuck in customs. As a result, the sensor came. Works. Everything is cool .. But the wire extension could give more.
