I have a basic question about jog frames and their intended purpose. I have created both tool and user frames in the past and I understand how they are applied and why they are valuable. I am not clear on when you would create a jog frame. For example, if I just created UF(8) then I can simply set the current user frame to UF(8) and the robot will jog aligned with that user frame. So when would I need to create a jog frame?
