Plug in the CDROM and I get a "READMEFIRST.TXT" file that says:
1) Click on Setup...
2) Then plug in the USB cable.
USB CABLE???? For a stepper motor driver?
Well, they have some really poor GUI for click-n-test that has NO documentation, will connect to ANY attached FTDI USB interface (Such as the FTDI cable I have running my arduino) and makes a general mess on things.
After a half-day, I got the darn thing stepping from the Arduino, but I'll have to figure out how to get it running without starting up the GUI and clicking boxes pretty soon.
