magnetic linear movement

[cjablonski]

Wondering if the mechanics of these systems would be at all advantageous in application on a shark and what's used to drive them, along with the complications of conversion. Have briefly reviewed thier availability just unsure if the g code would drive it. Additionally what forces would be required to ensure smooth operations with a router.

I'm not at all sure that it would be a workable application without adding the much mentioned "closed loop" devices to detect if movement is actually accomplished when commanded to. Although all things are relative, I am not sure that magnetic linear movement devices on the scale that is practical, would have enough power to accomplish driving the system. Again, there may be design potential but I think stepping motors are the best fit at this scale and type of design. Admittedly I am a little ignorant on magnetic linear motion so please excuse me if I am totally off base.
