I bought the 3-Axis Motor Controller from Marco Wong. (Here) Going by the specs, the board seems sophisticated, and reasonably priced. But the documentation is thin, badly worded, and missing bits. I'm in the process of re-writing the documentation for my own use, and I wondered if there is any interest in collaborating on it.
I think that documentation is part of the product. Producing a board with poor documentation is as bad as shipping it with connectors missing. On the other hand, clearly English is not Marco's first language.
I figure better documentation helps everyone and hurts no one. Is there any interest? If you use this board and can explain some of the missing pieces, let's talk.
