Does anyone know a good site to exchange information about making things with milling machines? I'm using the OtherMill, but I'm interested in learning about others.
I learned machining by subscribing to this magazine. They also have an excellent forum. There are also other metalworking forums Google will help you find.
I had to cancel my subscription years ago because I had TOO many magazines coming. But I still do machining at home and until November, did it at my electronic assembly service business.
If your machine is Arduino controlled this is probably a good section for you to be in.
Otherwise there are a lot of other more dedicated forums out there if you have a specific controller.
