Been Running Mach 3 on my router table for 5 years or so with no issues.
I have now converted my benchtop mill to 3 axis ballscrew and have purchased a ' Revolutionary 3 Axis Mach3 CNC USB Smooth Stepper Motion Controller Card 200KHz' which is USB to run from my Laptop. Ebay £106.00
No docs but did come with drivers so plugging it into the laptop was fine as the board was recognised and the wee red light comes on.
However this seems to be different from the Smooth Stepper discussed here.
Is there a special Plugin for this board
How do I tell Mach 3 to talk to the USB port rather than the Parallel port ?
Any help will be very much appreciated.
I have attached a PDF of the board ,
