When the B710 engraver was developed, OEE succeeded in creating one of the best and most reliable engravers around. However they did make one mistake.

Unlike a B720, whenever an operator wants to shut off the cylinder drive, he has to wait until the engrave head is completely up and stopped before pressing the cylinder drive button.

With this upgrade, the cylinder drive button can be pressed at the same time as the engrave button is pressed and the cylinder drive will stop automatically when the head is completely up.
