Description:
3D Printer Touch sensor 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.
3D Printer Touch sensor 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 3D Printer Touch sensor are the same as most auto bed leveling sensors, which consists of a RC servo and a micro switch, thus, 3D Printer Touch sensor can be used on almost every 3D printer control board.
By using progressively designed solenoid and hall sensor, 3D Printer Touch 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.
Features:
1. Simple
3D Printer Touch sensor can be easily applied, since it has a small and simple structure. Gathering information & firmware setting will be an easy task, because 3D Printer Touch sensor 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
3D Printer Touch’s sensor Standard Deviation in repeatability is around 0.005mm, at that precise.
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
3D Printer Touch sensor consists of ATtiny13A, solenoid, and a push pin.
6. Wide Selection of Bed
3D Printer Touch does not use either optical, nor proximity (inductive/capacitive) sensor.
3D Printer Touch is controlled by Hall Effect, providing high precision. Thus the bed material can be selected freely.
7. Optimized structure: Larger Build Size
3D Printer Touch sensor is a small and technology-intensive one. Build size can be set larger than other existing auto bed leveling sensor.
3D Printer Touch sensor uses existing RC Servo motor signal intactly, so just plug 3D Printer Touch sensor on the same pins after removing servo motor.

Note:
The 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.What’s more, this sensor is not compatible with some boards, such as Melzi V2.0, V3.0 and some board. Please note the wire connection and study if your control board supports 3D Printer touch sensor before order.
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 3D Printer Touch sensor 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.
