Okay. Be careful when snapping that the Orientation option is selected in Snap task pane, otherwise you would just snap the location. You can also change the snap to Frame, etc. to only select coordinate systems/frames like a tool frame. In most cases, always check that the Z-axis of the tool frame is pointing down or the direction that the gripper is facing down.
The tutorial is just about grasp and release not looping, so that’s why it is not covered. You could use a While loop, but a “simpler way” is to go to the Component Properties of robot, click the Executor tab, and then select the IsLooping checkbox. That will loop the robot program.
Your next question is probably how to make the batch conveyor receive more parts. Refer to the attached layout, which is the same layout I attached earlier, but with the IsLooping checkbox active, and a new Set Output signal in robot that sets the StartStop signal of the batch conveyor to True.
