I have a KRC2 KR150 KUKA robot. I had an issue with software limits and while trying to change them I unmastered the robot. I have no mastering tool. Is there a way I can return the robot to previous master settings?
It can be done by feel, using "Dial Mastering," if you press in the gauge pin with a plastic tool and VERY SLOWLY jog the axis in a negative direction. Stop the robot when you're sure you've hit the very bottom of the gauge target V-notch, and hit "Master".
However, this process is only as good as you are at feeling the bottom of the target V-Notch. It can be used in an emergency, but you really should get either the dial gauge adapter, or an actual EMT.
