@robot56 - I had to play around with mine for a while before I got them functioning the way I wanted. This included changing ports around, and which motor wires hook up to which connector. Are you working on an omnibot? When I get home I can give you the low-down on how mine is wired and how it is set up in ARC if that will help?

That would be a big help! I too am working on an omnibot. Looking at the pictures of of yours has been a huge inspiration to get mine done

Thank you so much

Which motor driver are you guys using?

It is a 2.5 amp motor controller that Dj had on the website for a week or so. I think it was on backorder after the first few days of being posted on the website! It's the same one that Dj posted the wiring schematic for on the first page. Robotshop.com has a very similar one for around $20
