Well here is a quick rescue.
http://www.fontspace.com has many many free fonts, many of which are dingbat style (graphics). I was amazed at one that i downloaded,
In ink-scape i converted a corner graphic to a path and it had 3900 vertex! Now that's a lot of detail.
you can use ink-scape or gimp to do this project, but I'm using gimp as its simpler and easier to understand for most people,
and does a very good job at this.
This project will teach you how to use a font (a dingbat style) to produce graphics for a CNC machine project.
Step 1: Use free software
or just use the fonts already on your computer.
open a new page, I'm using gimp ( a free open source program)
size the page the size you want the graphic to be, in my case its 5'x 5"
on the first layer decide if black or white will be the base or lowest cut your machine makes, and bucket fill that color
I'm doing black as the lowest cut.
