Geeetech 3D Touch – Sensor nivelador cama


Geeetech 3D Touch Sensor Leveling



Este dispositivo es un sensor de auto nivelación para camas de impresoras 3D el cual mide en forma precisa el espacio entre la cama caliente y el extrusor. Su instalación mejora significativamente la precisión de la impresora 3D.

Es un dispositivo simple, inteligente y preciso. Puede funcionar eventualmente sobre cualquier material de la cama, tales como vidrio, madera, metal y otros.

La función principal y controles son los mismos que usan la mayoría de los sensores de nivelación de cama, que consiste en un RC servo y micro switch, entonces este dispositivo puede conectarse en muchas tarjetas controladoras de impresoras 3D del mercado.

El producto ofrecido no incluye el soporte para montaje en impresora 3D en particular, puede obtener información en (en inglés) y la instalación en la página del fabricante (en inglés). Para servicio de instalación especializado, puede consultar para cotizar según el caso particular.


1.- puede ser facilmente instalado, dado que es pequeño y tiene estructura simple. La recopilación de información y ajuste del firmware es fácil, porque funciona como cualquier sensor de nivelación de cama caliente.

2.- Inteligente, 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

3DTouch’s Standard Deviation in repeatability is around 0.005mm, at that precise.

If you choose 3DTouch, your 3D printer will be high-class masterpiece, giving you an enjoyable experience.

4. Innovative Solenoid: Ultra Power Saving

On idle state, while the push-pin is whether pulled out or retracted, there are not any electric current flowing on solenoid, and standby electric current in the whole device is below 15mA on average, whereas on working state, while the pin is moving in sudden about 100ms, under 300mA flows in the device.

Low power consumption even further drops joule heating, preventing from heat problem.


5 Technologies

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


6 wide Selection of Bed

3DTouch does not uses either optical, nor proximity (inductive/capacitive) sensor.

3DTouch is controlled by Hall Effect, providing high precision. Thus the bed material can be selected freely.


7 Optimized structure:  Larger Build Size

3DTouch is a small and technology-intensive one. 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.


Please note that:
3D touch auto leveling sensor is not plug_and_play; you will need to do some modification to your
firmware and for some control board,
you may need to do some soldering work to the connector. We have prepared the pins for you.

Voltage: 5V

Current: 15mA

Max. Current: 300mA

Cable length: 150mm

Net Weight: 10g

Shipping weight: 25g


Operate condition

3DTouch can be operated in the following condition.

One I/O for control (PWM or Software PWM)

One I/O for Z min (Z Probe)

GND and +5V power



3-pin: Brown (-, GND), Red (+5V), Orange (control signal)

2-pin: Black (-, GND), White (Z min)



Additional power supply will be needed in case your board does not supply enough amperage.

Electronic devices can be damaged or even destroyed if connected to wrong polarity. [wrong terminal connect to 5V(+) and GND(-)]

Pulling/pushing hard on the push-pin can damage 3DTouch and make it less accurate.

Fix push-pin with locking paint after reassembling or adjusting core.

Do not remove or deform elastic material attached on the push-pin.
