Print head positioning using laser triangulation sensors
When printing on materials such as glass and ceramics, very fine detailed structures are generated, which requires precise positioning of the print head. This is why optoNCDT 1420 laser triangulation sensors from Micro-Epsilon are used. With a measuring range of 10mm, these determine at various points in the print head the respective distance from the surface to be printed. The sensor data is transferred via the RS422 interface to the control system. The data obtained enables the determination of the edges and the surface tilt and therefore the exact positioning of the print head.
