I have got the new TurtleBot 3. I have tried to follow all the steps mentioned in the documentation part http://emanual.robotis.com/docs/en/pl... . I have tried to bring up the turtle bot but then I am getting the error message.

Tried to publish before configured, topic id 125. Creation of publisher failed. Checksum does not match.

The ROS version I am using is Kinetic

Does anyone have a fix for it?

Can you please update your question with the full error and your code? As the question is right now, all I can say is that you're probably trying to publish a different message type than what your subscriber is expecting. Can't say for sure until you update your question.
