Omar, Thanks for helping us find this one. Me and Tyler (Lead software student) did not know that Motor Enable reset the counts. We must have missed that one while trying to learn about the Talon SRX.

This was a great mentoring experience for both software and electrical sub-teams. They learned how to use the o-scope and document problems along the way.

We will give this a try tonight and see if that wraps up our problem. Again, thanks very much for assisting us!

PS: You are right about self-test. I think from a troubleshooting stand point, we got focused on something slipping, or bad encoders because they were not new, is the reason we didn't think of doing that step as well. To look at what the drive module sees before any data is processed into the robo rio.

Will follow up one more time with good results tonight. I hope this troubleshooting journey helps others in a positive way.
