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 can work with nearly any type of bed material, such as glass, wood, 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 a more enjoyable printing experience there are many smart functions such as self-test, false alarm, alarm release and test mode for M119.

Product Features:

1. Simple

3DTouch can be easily applied, since it has a small and simple structure.

2. Smart

Self-test: The push pin is operated three times to test when the power is on
Alarm: The LED light blinks if a problem found on a self-test or on an operation.

3. High-precision

Standard Deviation in repeatability is around 0.005mm.

4. Innovative Solenoid: Ultra Power Saving

On idle state, while the push-pin is whether pulled out or retracted, there is no electrical current flowing on the solenoid, and standby electric current in the whole device is below 15mA on average, whereas on working state, while the pin is moving there is about 100ms, under 300mA flows in the device. Low power consumption even further drops joule heating, prevents overheating.

5. Technologies

3DTouch consists of Atmel ATtiny13A, solenoid, and a push pin.

6. Wide Selection of Bed Surfaces

3DTouch does not uses either optical, nor proximity (inductive/capacitive) sensor. Instead it is controlled by Hall Effect, providing high precision. Thus the bed material can be selected freely.

7. Optimized structure: Larger Build Size

Build size can be set larger than other existing auto bed leveling sensor. 3DTouch uses existing RC Servo motor signal intactly, so just plug 3DTouch on the same pins after removing servo motor.
