Description The 3D Touch automatic leveling sensor is a device that uses the Hall effect to achieve leveling. The position of the point can be obtained by touching the point on the heating bed, and then compensated by adjusting the Z- height during printing, so that printing can be realized even when the platform is uneven. Note: Due to different production batches, the wire color is slightly different.
