This should be a lobber,
So I have a robot that at one point could jog its external axis quite normally. It was disconnected, moved locations .. everything was reconnected. All of the data for the external axis is still in the controller (I checked axisconfigurator) and E1 shows up under Axis Specific in Monitor > Rob. Position...
... however, when I switch jogging mode from spacemouse to robot+axis, I can't change from just jogging the robot. IE: I have no external axis jog options under any user group??
