We've had a Multimate 3000 sitting on the floor for sometime now, unused. I got it up and running, and have even cut a few files, 2d and 3d. Now that I have the ability to change bits on the fly, could someone direct me to a good book or i-net source that would tell me what bits I need to use for different materials and finishes. I know, newbe question, but I've been using a 2d CNC and just cutting starboard and plexi for flat cuts, and thats all I know. Any direction would be appreciated.
