Thanks for fixing this. We have a multi-team design review tonight so we wont get to try this out until tomorrow but I am glad we can finally switch back from PWM control.

I had a chance to try it out yesterday and today, and it looks like the timeout issue has been fixed! Jag control seems to be rock solid. Thanks guys!

We tried this with Labview Open 4 motors with Can Jaguar and have the same issue. We may have bitten off more than we can chew with using the Can rather than PWM< but thought it would be the best way to minimize wiring.

We were daisy chaining the Jags, (4) for all motors, and when we enter ID 1, 2, 3, 4, motor 1 passes, but 2 thru 4 return the error. We can communicate to 1 jag with no issues, but the LAbView coed does not allow you to change the address for each individual motor. Always reverts to PWM by default for motor 2, 3, and 4. Maybe I am missing something, but had other eyes looking at it with me, and no joy!

Any experienced Labview folks tried this yet????

Error -52007 is fixed by adding a 0.050 second (50 millisecond) delay between motor speed commands to the Jaguar. If you Google this, you will find the original post on Chief Delphi (not my fix, but we tested this and it got rid of the -52007 error).

Hope this helps!
