Operates at 5V, springless mechanical drive, includes 1 m cables and simple connection on 3 control pins and 2 Zmin pins. Sensor that allows adding the autolevel functionality to 3D printers. This accessory makes it possible to detect the position of the bed on the Z axis in several points so that the distance between the print head and the printer bed is always the same, partially eliminating the need to manually bring the bed to level with the print head. since the printer will always correct the position of the Z axis during printing according to the distance detected by the sensor, it is still recommended that the bed be leveled manually from time to time, so that the movements of the axis are minimal. This model is the one without spring .
