Abstract
A 3D printing nozzle calibration system, comprising a heated chamber; a printing base plate mounted inside the heated chamber; printing base moving means configured to move the printing base plate; a moving carriage; at least one rail on which the moving carriage is configured to slide up and down; a printing nozzle partially mounted inside the heated chamber; the printing nozzle is connected to the moving carriage; a hard stop connected to the moving carriage; a fixed part on which the hard stop is resting; and a printer controller; wherein the printing base plate is configured to move up, up to a point where the printing base plate touches the printing nozzle in a determined point of the printing base plate, thereby causing the hard stop to disconnect from the fixed part; and wherein the printer controller is configured to store a height of the printing base plate upon the disconnection.
