	Have you considered power scaleability by attaching 2 (or more) double-shaft motors one behind the other? That would be a good feature for high power, such as lathing, or even adopting a similar design to milling.

That would be a useful feature from the standpoint of scaleability. This would be quite exotic to have, and I always aim for such.

The Y and Z axes would be made from aluminium bolted together. The reason for the steel frame is to get maximum support and stability if the axes are moving fast.

	The reason for linear bearings and screws on the X axes is so i dont have to move a big and vibrating motor with the axe. This is propably the biggest motor on the table. Also using the design that torchmate uses then we need 2 motors on both sides.

	The most expensive part of the controller board are the power transistors. If one didin't need the 30-50V 6A output then we can change to smaller transistors. Also i have dedicated stepper motor IC's to control the critical timing so its a bit more expensive then using a generial purpuse microcontroller like most designs use, but thous designs can't step really fast. Also many other "open" router table designs still relay on proprietary controllers.		The most expensive part of the controller board are the power transistors.

	The controller board has a small 8-Bit AVR to communicat with the dedicated IC's and a computer. I haven't started the code but its really simple and written in C and small parts in assembly. The controller will communicat thru RS232 or Ethernet (if we add that option, and it would be really nice to have). The controller will be able to take in simple commands like "Move this axe to position X at Y speed", so it will be able to work standalone without Smari's routing software.
