Hi ,  
We just got a new UR5e. So we are a fairly new user.  
We are trying to use UR5e with ROS.  
We installed URCap on Teach Pendant.  
The UR5e node is launched by  
roslaunch ur\_robot\_driver ur5e\_bringup.launch robot\_ip:=192.168.1.145 kinematics\_config:=${home}/nex\_ur5e\_calibration.yaml

When we try to run Externalcontrol, we get following error

 ![URCAP_crash](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/7/750f062fbd3853ca5a457643a300c08ac4a4fdb5.jpeg)

On ROS side the UR node is unable to execute movement command with following message.

Can you please guide us in uderstanding why the Externalcontrol URCap is crashing and how to fix it?

Thank you!
