In the graphic below, notice we led in from the center of the hole at 90 degrees.

(Refer to point 1 and red code).
The M57 inserted before the M65 tells the controller that we are going to use the encoder
for height control. The encoder height value can be optimized to give us the best cutting
height for the hole which may be different from standard contour cutting. After the
piercing routing completes, the machine will lead into the contour at 90 degrees and

continue in a counter-clockwise direction to cut the hole. As the machine approaches the
lead in kerf, there are a couple of different things we can do. One is to use the M174. This
