Wide range of applications: Our upgraded version of the 3D printer accessory hot bed leveling sensor kit is suitable for Ender 3 / Ender 3 Pro / Ender 3S / Ender 3 MAX / Ender 5 / Ender 5 Pro / CR-10, with 32-bit V4.2.2 Or V4.2.7 motherboard.Low power consumption: In the standby movement, whether it is withdrawn or retracted, the standby current of the solenoid valve without current flow is less than 15ma. In the working mode, it suddenly rises to 100ms/300ma. Low power consumption to avoid heating problems. Please keep away from magnetic parts such as powerful magnet motors and fans when installing.High precision: for 3DContactautomatic bed position sensor realizes simple structure and high precision through gradually designed solenoid valve and Hall effect control. The standard error of repeatability for 3DContactis about 0.005 mm, so it is easier to use and improve the forming rate. Therefore, you can choose the platform board according to your wishes. Compatible with ABS, PLA, glass, metal, plastic and all materials.Easy to use: for 3DContactis a 3D printer auto-leveling sensor based on open source, small and simple, easy to use. Since for 3DContactcan use the automatic bed sensor as usual, it is easy to collect information and set up the firmware.Strong compatibility: 3 different mounting brackets can be installed on multiple 3D printers. The 3D printer is automatically horizontal, small in size, simple in structure, and prints when connected. It can accurately measure the inclination of the hot bed and automatically compensate the Z axis, easily avoid printing failures caused by uneven hot beds, so that the printing is stable and unchanging.Product name: automatic leveling sensor kitSensor size: 40x25mmFixed bracket: 38x20mmL-shaped fixed bracket: 35x24mmT-shaped fixed bracket: 30x16mmColour: picture colorMaterial: ABS+metalPackage Contents:1 set * Automatic leveling sensor1 * Sensor bracket fixing part1 * Automatic leveling probe1 * Fixed bracket L type1 * Fixing bracket T type5 * Black cable tieOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
