6. Set the working coordinate origin
Before running the G code program, you need to find the position of the engraving figure relative to the overall
engraving plate. There is a three-axis coordinate system in the visual graphics. The origin of the three-axis coordinate
system is the tool setting point of the actual processing graphic. You can move the tool to determine the position of
the engraving graphic relative to the overall engraving plate based on the position of this origin. The engraving figure
in the figure below is taken as an example. After the selected tool position is started, the X, Y, and Z axes are reset to
zero (the axis is reset to zero, and the Z axis is reset to zero buttons). Before returning to zero, make sure
that the tool approaches the distance of one sheet of paper for engraving, and then return the X, Y, and Z axes to zero
(please use a flat-bottom sharp knife when engraving, and use a cylindrical milling cutter when machining planes,
slots, and holes) The effect is that the sculpted figure will be carved with the blade tip as the origin.
