1、Simple. 3Dtouch can be easily applied due to its small size and simple structure. Collecting information and firmware settings will be an easy task as 3dtouch works as an automatic bed leveling sensor as usual. 2、Smart. Self-test: Push the nail operation three times. Alarm: LED light flashes if a problem is found in the self-test or operation. 3、High precision: The standard deviation of the repeatable 3dtouch is about 0.005mm, which is accurate. 4、Innovative electromagnetic, super power saving. In the idle state, while the push is pulled out or retracted, there is no current flowing solenoid valve, the standby current of the whole device is lower than 15ma average. While in the working state, whil 5、Bed width selection: 3D Touch does not use any light, nor close to (inductor / capacitor) sensors. 3D Touch provides high precision through Hall effect control. Therefore, the bed material can be freely chosen.3D-touch is a fully automatic universal 3D printer hot bed leveling probe (automatic leveling probe). Its advantages are simple, compact, high precision and good compatibility. It is compatible with all bed materials, such as glass metal. Wood plastic acrylic and so on.Features:1. Simple. 3Dtouch can be easily applied due to its small size and simple structure. Collecting information and firmware settings will be an easy task as 3dtouch works as an automatic bed leveling sensor as usual.2. Smart. Self-test: Push the nail operation three times. Alarm: LED light flashes if a problem is found in the self-test or operation.3. High precision: The standard deviation of the repeatable 3dtouch is about 0.005mm, which is accurate.4. Innovative electromagnetic, super power saving. In the idle state, while the push is pulled out or retracted, there is no current flowing solenoid valve, the standby current of the whole device is lower than 15ma average. While in the working state, while the foot walks, suddenly up To about 100ms, the device that flows under 300ma. Low power consumption even further reduces Joule heating to prevent thermal problems.5. Bed width selection: 3D Touch does not use any light, nor close to (inductor / capacitor) sensors. 3D Touch provides high precision through Hall effect control. Therefore, the bed material can be freely chosen.6. Optimized structure: Larger size. 3D Touch is a technology intensive person. The build size can be set larger than other existing automatic bed level sensors.Specifications:Cable: 3D-touch CableWiring 3Pin: Black ( -, GND)Red (+5V)Blue (control signal)2PIN: Black ( -, GND)Yellow (Zmin)Package List:1 x 3D-touch probe 2 x M2.5 screw 1 x M2.5 nut 1 x 2pin female to female 1m 1 x 3pin female to female 1m 1 x Screwdriver1 x Connection LineNote:Some 3D printer motherboards may have an external 5V power supply if there is insufficient 5V power supply which leads to situation where the probe is difficult to push out, or the logic circuit protects the master restart during operation. If encountered, it is generally recommended to use the DC-DC buck module to draw power from the mains.1.+5V and GND should not be connected for a long time.2. Please try to stay away from strong magnets, motors and fans, etc. with magnetic components3. Accidental impact on the probe aluminum rod may damage or affect the detection accuracy4. Adjusting or reassembling the set screw of the probe requires threading glue5. Install the probe to avoid deformation of the casing6. Pulling the aluminum rod hard will damage or affect the detection accuracy.
