OK, I thought I could work this one out myself but nope.
I installed mach 3 (but haven't bought it yet), I ignored the disk that come with the machine as I have nothing to read it.
Turned on the controller box.
I plugged the parallel to usb cord into computer (Microsoft surface book). It was identified.
Opened mach 3.
NOW WHAT? I cannot see any evidence that the computer is communicating with the steppers/spindle at all. Do I have to install drivers? What can I do to test this?
