Product Description:

Geeetech 3D Printer Auto Leveling Sensor 3D Touch for 3D Printer Improve Printing Precision
1. 3D Touch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of your print surface.
2. It can greatly improve the printing precision of your 3D Printer.  
3. 3D Touch features simple, smart and precise. It could work with nearly any kind of bed materials, such as glasses, woods, metals and so on.
4. The main functions and controls of 3D Touch are the same as most auto bed leveling sensors, which consists of a RC servo and a micro switch, thus, 3D Touch can be used on almost every 3D printer control board.  
5. By using progressively designed solenoid and hall sensor, 3D Touch can integrate high precision in such a simple structure.
6. 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.

1. 3D Touch can be easily applied, since it has a small and simple structure. Gathering information & firmware setting will be an easy task, because 3D Touch works as usual auto bed leveling sensor.
2. Self-test: The push pin is operated three times to test when the power is on
3. Alarm: The LED light blinks if a problem found on a self-test or on an operation  
4. 3D Touch Standard Deviation in repeat ability is around 0.005mm, at that precise.
5. If you choose 3D Touch, your 3D printer will be high-class masterpiece, giving you an enjoyable experience.
6. 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.
7. Low power consumption even further drops joule heating, preventing from heat problem.
8. 3D Touch consists for Atmel ATtiny13A, solenoid, and a push pin.
9. 3D Touch does not uses either optical, nor proximity (inductive/capacitive) sensor.
10. 3D Touch is controlled by Hall Effect, providing high precision. Thus the bed material can be selected freely.
11. 3D Touch is a small and technology-intensive one. Build size can be set larger than other existing auto bed leveling sensor.
12. 3D Touch uses existing RC Servo motor signal intactly, so just plug 3D Touch on the same pins after removing servo motor.

Voltage: 5V
Current: 15mA
Maximum current: 300mA
Cable length: 150mm/5.9''
Weight: 25g

Operating conditions:
3DTouch can run under the following conditions:
A I / O (PWM or software PWM) for control
A I / O (Z probe) of Z min
GND and + 5V power supply

3 Pin: Brown (-, GND), red (+ 5V), orange (control signal)
2 Pin: Black (-, GND), white (Z min)

Warm Tips:
1. If your circuit board is unable to provide enough ampere number, additional power will be required.
2. If connected to the wrong polarity, electronic devices may be damaged or even destroyed. the wrong terminals are connected to 5V (+) and GND (-)
3. Pulling / pushing on push pins may damage 3D Touch and make it inaccurate.
4. After reassembling or adjusting the core, fixed push pins with locking paint.
5. Do not remove or deform the elastic material attached to the push pin.

Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
