3DTouch auto leveling sensor
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.
Please note: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.
For detailed instructions, please refer to the user manual. If you need any help, please feel free to contact us.Thank you.
Features:
1 Simple
3DTouch can be easily applied, since it has a
small and simple structure. Gathering information & firmware setting
will be an easy task, because 3DTouch works as usual auto bed leveling
sensor.
2 Smart
Self-test: The push pin is operated two 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.

One I/O for control (PWM or Software PWM)
One I/O for Z min (Z Probe)
GND and +5V power
Caution
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.
