Hi everyone, I am using Python to get data from port 30003. When the TCP is moved, the values for the rotation vector on the polyscope UI and port 30003 show a huge discrepancy. Examples: ![image_8](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/1X/84cbdb78cacadfd7f5bf5ecf4c80f4c7bc127609.jpg) ![image_9](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/1X/0dade95d9d0a46b956ddae3a54c07b55eb521251.jpg) ![image_7](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/1X/8a75afed2350e6f2f856ecb45219d65a288daffa.jpg) Can you help me understand the problem? Thanks Ben ---

I reckon that [this topic](http://forum.universal-robots.com/t/discrepancy-of-pose-from-30002-and-pendant-reading/238) refers to the same issue. ---

Thanks for the pointer!
