General Mach Discussion / Re: usb to parallel

Might be worth you guys without parallel ports waiting a few more weeks then getting a Smooth Stepper, its USB and does the pulse external to the computer. It will do up to 4MHz per axis and is ultra clean compared to the software/parallel pulse. I have been Beta testing the Smooth Stepper and its working great, should mean you can basically use any computer (laptop etc) as all Mach has to do is the calcs and not worry about the pulses. I have had the Smooth Stepper running from a pico motherboard (total size of pico is 100mm x 70mm) its 1GHz embedded CPU and I have 1GHz memory in it. I will be using this setup in my Beaver mill that I am retrofiiting at the moment, another great thing is I will be able to use the 2000line encoders that my motor/drive combos have without having to resort to the drives electronic gearing
