Hi all I know this is going to be a dumb question I haven't had time to research it fully so I thought I'd ask. So here are my question I was looking at the Gecko G-Rex G100. This uses the usb port to get instructions from the computer? I believe I need to use stepper drivers like the gecko 20 2connected to the G100, 1 for each stepper . Will Mach 3 or 4 work with it, if not what kind of software will? The laptop I want to run this off of has only usb ports and an expresscard 54/34 slot on it. I would appreciate any help. thanks in advanced Lloyd
