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
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.
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.
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
3DTouch’s Standard Deviation in repeatability is around 0.005mm, at
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.
3DTouch consists of Atmel ATtiny13A, solenoid, and a push pin.
6 wide Selection of Bed
3DTouch does not uses either optical, nor proximity
3DTouch is controlled by Hall Effect, providing high precision.
Thus the bed material can be selected freely.
7 Optimized structureLarger 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.

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(-)]
