Feature:1. Strong compatibility, capable of intelligent self‑checking, easy to apply2. Small size and compact workmanship, easy to install on 3D printer, convenient to operate3. Can make it easier to level the hot bed, and can accurately measure the inclination of the bed surface4. Using automatic leveling function, it is more convenient to use and improve the success rate5. The product is an automatic level sensor for 3D printers, which can be used with any kind of bed material, such as glass, wood, metal, etc.Spec:Item Type: Auto-Leveling ModuleMaterial: Aluminum + PlasticModel: 3D Touch upgrade kitApplicable Models: For Ender-3/Ender-3pro/Ender-5/Ender-5proTouch Color: BlackPackage List:1 x 3D Sensor1 x Memory Card Converter(adapt to for Ender-3 V4.2.7 version mute motherboard) 1 x Connection Line1 x Bracket2 x Cable Tie1 x Wrench4 x ScrewNotice:Some 3D printer motherboards have insufficient 5V power supply and may require an external 5V power supply, which shows that the probe is difficult to push out, or the logic circuit protection main control restarts during operation. If encountered, it is generally recommended to use a DC‑DC buck module to take power from the main power supply.1. +5V and GND should not be connected reversely for a long time, it may burn2. Please try to keep away from strong magnets, motors, fans, and other magnetic components3. Accidentally hitting the probe plastic rod may damage or affect the detection accuracy4. Adjusting or reassembling the set screw of the probe requires thread glue5. Please avoid deformation of the shell when installing the probe6. Pulling the aluminum rod hard will damage or affect the detection accuracy
