Hi guys, my budget is around £400-£500. I was initially hoping to build something like this: http://www.mycncuk.com/threads/1541-...-framed-router and work on using it for carving and stuff like this http://www.youtube.com/watch?v=VhKl0...IyoicGWeJ5Z1gQ making use of roller carriages instead of supported round rails as shown here http://www.youtube.com/watch?v=5dmPV7TyzPg as precision is not a high priority for my build but not sure if this is possible with my budget. If not, I would be more than happy with a small router for carving work as shown in my previous post.

As mentioned, I can get box section (both steel and aluminium) and things like fasteners, welding equipment, sheet metal all for free from work. Also, I have an Arduino Uno which could run GRBL and connect directly to the drivers, so might be an option for a controller.
