Hi Guys,
............................... I am using a smooth stepper connected to a C32 BOB........................Hopefully someone has used this setup besides me!.......................
Hi there I don't have the Vipers but the C32 BOB and SS setup I do have, and as Jeff suggested you are the only one who knows what Ports & Pins configuration you have selected.
But regarding the two boards once you connect them via on board connections blocks and then power the boards correctly, it's just a matter of selecting which pin no and from what port etc....but you must also have the seccond port selected in Mach too.
The SS shouldn't make any difference or physically alter your Ports & Pins settings as the SS simply put just replaces the Parallel Port only.
In your post you suggested that the LED on the SS board are bascially doing what their supposed to do and in the correct sequence of events and once the SS red LED flashes fast that shows that the Firmware is correct and Mach is definitely communicating with the SS.
A suggestion here is to have a closer look at your set up in the Mach Ports and Pins window and verfiy that no two pins numbers are selected for different applications...
I'm not sure if this advice was what you were seeking if not reply.
