Thanks for the quick reply. I understand I’m not using the normal hardware, so I greatly appreciate the help. I downloaded the extension from this website, but the arduino side is from the Sphere-o-bot website.
I’ll take the ramps board out of the equation and try it again. Is there any arduino-based solution that is officially supported or just the EBB driver board?
Like I said, thanks again for the “unsupported” help.
