Abstract: A laser assembly includes a removable work table defining a planar work surface. A frame is configured for supporting the removable work table with the work surface in a work surface plane. An X-Y beam transport is operatively associated with the frame and is configured to direct a laser beam from a laser beam source to X-Y coordinates relative to the frame. At least one clamp is operatively associated between the frame and the removable work table with each clamp having a clamping position for clamping the work table to the frame with the work surface in the work surface plane in a release position or removing the work table from the frame. A void underlies the removable work table and is operatively associated with the X-Y beam transport with the removable work surface removed. A X axis control member moves the work table along a Z axis normal to the work surface plane between a proximal position near the X-Y beam transport and a distal position away from the X-Y beam transport.
