Printer filament feed monitoring

Abstract:

A filament feed monitor and method of remediating a printing error in a 3D printer is provided. The method may include detecting motion of a trailing gear by an optical sensor. The printing error may be detected by a controller connected to the optical sensor in response to a determination that rotational motion of a filament feed roller has exceeded a predetermined threshold, which may be determined based on the detected motion of the trailing gear. A command may be generated and executed by the controller to remediate the printing error.
