Making Motion 89
For the second shape, instead of providing a new set of X and Y
coordinates, a jog statement is used to shift the Y axis 3 units. You
can then provide the same coordinates used to cut the first shape.
The new starting position becomes coordinates (0, 3).

To cut the third and fourth diamond shapes, jog statements again
shift the starting positions for axes X and Y. After each jog statement,
the coordinates of the first shape are reused.

So what is happening? Each motion profiler calculates its own
commanded position, which is sent to a summation point. The
coordinated move, jog, gear, and cam data is combined for each
axis to create a setpoint.
