I pulled in a logo and was attempting to trace it. A coarse grid put the lines at times way off the image I was tracing and really made a mess of curves. The really fine grid was the ticket.
I have Inkscape. I've used it on and off over the years since it first came out. But I've never dived into it seriously. I've been lusting for a CNC since the Shapeoko was in its first design stage, so I've looked at tons of software over the years. The learning curve on a lot of it is pretty steep, especially if you want to do any 3D stuff.I was looking recently at the CNC that is sold at Woodcraft, and that uses VCarve, but I'm not entirely sure it provides anything over and above what Inkscape (and Shapeoko) can do.
My first project would be some scoretracks that I provide along with a product I build as a hobby and sell. The scoretrack is similar to a cribbage board and that was pretty simple to do in CCreate. I make about 100 of these a year and standing in front of a drill press drilling 42 holes in each is kind of an ordeal. I've also used Makercam.com to do it in the past but I've never really had the CNC to see if it would actually work
