Error while trying to control 2F85 gripper with a UR5

simonb9

Hi, when I'm trying to close/open my gripper in my program, I get this error: "An error occurred in the running program": "Index out of range, the list size is smaller than 4". The script code crash at line 1953: while(rq_read_sta_req[index])

I was using this gripper on my UR10 earlier this week and it was working without any problem. I tried to use the gripper mounted on a wrist camera and without the wrist camera. I have updated my Polyscope version to the most recent versions, same for my gripper UR cap. I can use the gripper manually with the gripper Toolbar. I just cannot call URCap functions in my program like "Gripper Move50%" or script function like rq_move_and_wait(150).

Any suggestion what else I could try to fix this problem? Thanks for your help.

For anyone wondering the cause of this issue: In this case, a global variable was named "Index" which was already used by our gripper URCap. Renaming this global variable to something else solved the issue.
