I don't mind so much someone selling my software on a CD. What I do mind is that they changed the name to trick the buyer. Perhaps I should be using a different license.

Why is it significant that this post was from a woman or that she has red hair? This comment sounds like a backhanded compliment, at best.

Another way to go Open-Source for a lot less money (~$1500) is to buy a K40 on EBay and refit it with a Buildbotics controller.

The other day I needed a faceplate for an outlet with a circular 240v US dryer plug and a two port 120v US plug. I couldn't find anything at the hardware store that would work but I found drawings for the junction box and plugs online. After an hour or two with LibreCAD and CAMotics, I was ready to LASER cut my faceplate from 1/4" poplar. I was really happy when it fit exactly the first time. Now I keep looking behind the dryer to admire my handiwork.
