Our calibration thorns made of steel have become stump (not hardened). We run the calibration at low speed but the robot pressure is sufficient to kill the tools. Two questions: - Is there a parameter setting or a rapid instruction to reduce maximum robot pressure during manual operation mode? - Supposed, the robot is stiff and it presses on the calibration thorn: Does it teach t real surface contact location or does it teach the the position inside the collision zone where it was to got to? Regards and thanks, Tobias ---

What are you calibrating? Does it require the robot to touch them or are you driving a teaching something, i.e. a TCP or work object? Or are you expecting the robot to push against them to calculate a location as you would do with a measurewearL for a weld gun? If it is something like MeasureWearL there is a touchforce variable to decrease the pressure the robot presses against the target with. Also if you are just jogging, you can turn down the motion supervision.
