Hey All

I had an unfortunate breakin and my the computer that ran the cnc was stolen. It had the NCStudio card in it. I am thinking to go to Mach3 so i can use a laptop.

I see there are many on the market. Which should I get and what difference is there between 50hz, 200hz and 400hz in terms of functionailty? What do i get with a 400hz that i don't get with 50hz?

Thanks in advance.
