I want to attach the workpiece to the robot and machine it with a standing tool (like a milling operation). I tried the Robhold true/false commands, but they were unsuccessful. I want to define targets on the workpiece and have these targets touch the tip of the stationary tool. How can I do this?

Did you teach the TCP after declaring it Robhold FALSE? The workobject origin isn’t as important as declaring it Robhold TRUE.
