I am trying to determine the details of various pins on the control and motor boards. Having the board diagrams or a diagram that has details about the pins will make it easier to wire sensors etc.
Have you tried here?
Already checked there. It has circuit schematics but not the board layout.
I had the same issue. I found the instructions very limited so I tried to work out a diagram that helped me work with it.
I have published it on my (new) blog at http://fabcirablog.weebly.com/
I am not an expert, so I can have made mistakes. If you find any, please let me know.
