Hi this is my first post here and am verry intrested on making a homebuilt CNC for stuff like small Aluminum parts. I have seen many home made designs and most are MDF board but I dont know if that will presicly cut aluminum.

I would like to build a small presice machine 3 axis to cut small aluminum parts, none of the axis will have to travel more than 12".

I do have a Mig welder and good welding skills, and many tools, I do whant to spend as little as needed probably around $500

Any recomendations?
