The Smoothstepper looks like a nice bit of gear. However, I think it is priced out of the range of th hobbyist starting off with CNC.
The SS is priced at $US155. At the moment I am valuing my currency ($AU) at $AU1 = $US0.60. That puts the SS at $AU258. Then there's postage and handling which could amount to $US28. That puts it at $AU305. For that money, I can buy a good, secondhand PC on which I can run my draughting and motion control software.
The only trade-off is that the PC has a large footprint, and like Wongster, my available space is limited. I could buy a 2nd hand laptop, but laptops with 25 pin printer outlets are a bit dated.
Good on the SS people for working to solve the Mach3/USB problem. I think it will be a couple of years before sales volume leads to a drop in price.
