Thanks for the info. We didn't even realize that we HAD 2 different types of encoders (can't find anything that says 360 on it other than a couple of disks once we get them magnified enough). We found that we had 1 250 and 1 360 disk on (which explains the ~50% higher reading on one side than the other). Seems that a 360 disk will work on some 250 encoders (maybe not reliably or at high speeds).

Replaced the 360 disk with a 250 and everything is working as expected. Now the programming team can work on creative uses for encoder data...

Thanks,
Kenton
