Hi all,  
I am having some issue with a UR5 CB3 cobot  
the application is case erecting using a manual erector  
the cobot is pushing the cartoon into the erector to open it and close its down flaps  
at some point, the cobot has a protective stop due to the resistance of the box to move along the erector  
we tried to reduce the safety restrictions but still having the problem  
any recommendations about this issue?

Are you using a force move or just a regular move?

Read your user manual explaining the force move node.
