Interesting design of commercial/custom machine
There's a listing on eBay for a very interesting looking router/plasma machine. Take a look at these pictures ...
There are two other machines on the pages linked from the eBay listing:
They appear very creative, though I don't know how well they work. The carriages with the direct-mounted motor are really neat.
In the last machine (32x32) the mounting of the x-axis rails above the gantry is different. I haven't seen anybody do that before (not that I've seen all the machines ever built though).
Very interesting indeed...
