After more than 5 long years, I wanted to say thank you to everyone who posts on this board. I have been a lurker quite often and typically used email over board posting, so my numbers are quite low. But the information and people on this site make it one of the best cnc resources on the web.
My recommendation for anyone wanting to get into CNC is to just just dive right in. Any way to get your foot in the door will start you on your journey. I started off with just a couple years of electrical engineering drafting under my belt. Then taught myself MasterCAM out of a self study book in the evenings, learned G-code on my own, then convinced a machine shop to give me a chance. I excelled to third year pay after only 3 months because I put my heart and soul into every machine cycle. I have a background in computer programming and this no doubt gave me the edge and a foot in the door to get rolling, but it was through the shear persistence that I prevailed.
I have been programming Komo CNC's in the woodworking industries for over 4 years now and provide contracting services in AutoCAD, Cabinet Vision, Cabnetware, Komo RouterCIM, ArtCAM and anything else related. All this in only a couple years. There is nothing like carving a $1500 per sheet of Corian and having a custom professional product under your belt.
Follow your dreams. Do what you love and the money will follow. And when in doubt, run the simulation first!
In my spare time, I author a technology website: www.smrt1.ca
Any questions, feel free to drop me a line.
Cheers,
