Can you send me the complete VB.Net project so I can test it on an actual board. Without seeing what RoboCmd does I cant say why the program is freezing up on you. While you are waiting for me to test that(after you send me the project) please run the same test using IonMotion(eg Position Settings w...

We do not have pull-ups hardwired on the Roboclaw because there is no standard to interface to encoders. Some encoders drive high and low and some are open drain. Some may need 3.3v pullups and some may need 5v pullups.

USB is a direct connection. Each USB port is seperate from each other so no commands from one port will be sent to the other port(unless you tell the PC to do that). What are you using to communicate with the Roboclaw(one of our libraries, eg python) or something you have written from scratch? Pleas...

The mixed mode compatibility commands require at least one forward/backward command and one trunning command before it will start running the motors. The Roboclaw uses these two values to determine how to mix the movements of the motors. For example if you send a forward command of 50% power and a t...

That is fine. We can continue through emails instead of that is what you prefer.

That should be ok. Th ebatteries for the most part will be providing the power and handling the Regen and the Power supply will basically keep the batteries topped up.

What are you using to talk to the Roboclaw? Also please prove the program you are using to send command 67 so I can run a test on it.

I beleive I talked with you yesterday. Based on what you said then and in this post we arent certain what caused the problem, though shorting the motor wires together is never a good idea. I beleive you are sending the board in. Based on the description the repair should be simple(no significant dam...

Noise is the typical cause of CRC errors. Please check your encoder outputs and the 5v line going to the encoders while the motor is running with an ocillascope. We have seen several motors with built in encoders with serious noise problems caused by improper snubber circuits on the motors. The fix ...

That is one of the dual mosfet packs. All the current flows through those so they heat up the most. If the board reached 100C before failing then my guess is the current sense was not reading correctly and let the board continue to heat up until it reached our max cut off of 100c. Normally from 85c ...
