I would like to know which scenario is used by the controller . Suppose the laser head is sweeping across and comes to the end of the drawing. There is a certain time - distance where the head comes to a stop and changes directions. Also the gantry moves to a new position during this time. When does the controller tell the gantry to move?
1. does it start moving as soon as the last dot is done and the head is still in motion?
2.Does it move as soon as the head comes to a stop and then both axis accelerate from a stop
3. Does it move as soon as the head comes to a stop and the head waits until the carriage moves before it accelerates?

Hope this makes sense
