Engraving Focus Offset Calibration

Before We Start

Before we start, let’s take a deeper look about focus offset.

Focus Offset: A parameter in order to optimize the result of shading. Each machine only has to change this parameter once. Note that we don’t have to adjust this parameter for different material.



1. Put the kraft paper (NOT the corrugated paper) from the manual pack on the center of Metal Base Plate. Tape the kraft paper firmly on the Metal Base Plate. Please refer to figure 1. 



Figure 1


2. Set the FLUX Studio to Engrave mode as Figure 2. 

  • MATERIAL: Kraft Paper
  • FOCUS OFFSET:  0mm
