I wrote a URCap program, and the start function is being triggered in the Activator script. This is causing a popup to appear whenever the UR starts. Because of this popup, the UR gets stuck at 100% but the teach pendant won’t move past the loading screen. Is there some way I can remove the URCap from the UR without the teach pendant? I am using a 3e.
