Hi,


Your code might have modified DYNAMIXEL configuration.

For example, accidentally changing ID or baudrate or operating mode may cause such issue.

DYNAMIXEL Wizard 2.0 provides various useful tools to check your DYNAMIXEL and recover the module to a factory default settings

Thank you.

We use proctol 1.0 and as you can see in the attached photo, the serve gets recognized in dynamixel wizard but when we try to write a position to it on Labview it executes the first iteration and then when we change the value, it does not get updated. However on the wizard it works fine. I can’t find how to reset settings to factory configuration in the link or on wizard. Any advice how to do so? Your prompt response would be appreciated. Many thanks in advance

You can find how to recover the firmware in the below page, but since your code works at least once with your DYNAMIXEL, firmware recovery isn't needed.

Have you also tried running the default example provided in the DYNAMIXEL SDK?

When quiting the Labview example, make sure to click the [Quit] button to stop the demo or else the serial port will be held by the software.


Thank you.
