Abstract: The embodiments include a system, comprising: a scanhead with a marking laser having a marking field. The system includes a vision system having a camera embedded in the scanhead having a field of view (FOV) within the marking field and an autofocus module which uses pixel information in an in-focus region of interest (ROI) of a target surface of a part to obtain a Z-axis focus in a vertical dimension above a two-dimensional (2D) plane. The marking laser selectively marks with a laser beam the target surface in the marking field based on at least the Z-axis focus.
