I for one have been been imagining a 3, 4 or even 5 axis VMC that fills the void between the Nomad (65 lbs.), Pocket NC and Tormach 440 (~500-700 lbs.) Made up of 3 sub-assemblies, 100 lbs or so each for the machine itself to allow for standard transport and setup. The Tormach requires a pallet jack and cherry picker. It would be a rigid machine with ball screws and linear guide rails, brushless spindle, tool changer etc. I think the reason it hasn't been done before, at least a 3 axis, is that at the hobby level market it's hard to find a profitable price point and the work envelope is either too small or way too large and compromises need to be made. A Nomad is $2,500 and a base Tormach without enclosure or stand is only about $5,000. I don't think people who are serious about CNC have a problem paying that money, but for small business and home users the noise could be a factor. I could see a smaller, much more rigid and powerful machine being popular. A high speed spindle running small tooling capable of cutting aluminum and steel efficiently. Something resembling the Othermill or Boxzy where the enclosure doubles as a structural member with industrial grade components, and options for adding ATC, coolant, probing etc. I don't think $5,000 - $7,500 is unreasonable to ask for that capability.
