As previously noted, customer selected custom fonts may be used when using the Marker Font
Generator feature. To construct these font files, certain guidelines should be adhered to.
1) Programming format must be EIA
2) Only M09 and M10 maybe used to enable and disable the marker.
3) Only G00, G01, G02 and G03 codes may be used.
4) The program must end in an M02.
5) The proper file name must be assigned to the font program.
6) The font program must begin in the lower left and end in the lower right.
7) Font programs should have the consistent dimensional limits (i.e. 1’ high, etc.).

The darker lines in the drawing represent the Traverse segment and the lighter lines represent the
Marking lines. You can see by this illustration that at the end of the font program, a traverse is used
to continue motion to the bottom right corner.
Note: The Burny 3/5 style of programming for the Marker Font Generator feature is also supported
for the default internal font source.
