Hi Mark,

Thanks for reaching out, the error appears to be originating from the Universal Robotics software so we are unable to look up the error code we are receiving. I’ll include the documentation we have regarding the URCAP plug-in below.

I just loaded the URCap on our CB3 UR3, and I do not get an error when running an unrelated program, but I do not have a Cognex camera, either.
But I don’t believe the error is in the controller. You could do a reinstall of PolyScope, and then it should definitely clear it up. It’s not too big of a job. :slight_smile:

Alternatively, you should find someone else with a CB3 robot and a Cognex camera to test the same setup at.

Hello EFN,

I tried to re-install UR Software Version 3.15.8.106339 but the UR says that “This update is the installed version!”. Do I need to erase some file/s?

thanks

It’s a little more complicated than that, I’m afraid. You can find a tutorial here: https://www.universal-robots.com/media/1804841/install-new-image-all-types.pdf

There is another way to get the camera to function with the Cobot without using the URCAP. If you would be interested in this, let me know!
