It's time to add a relay on the out pin of my Flip Flop.

According to the schematic, i connected the Collector pin to the input of relay:

Now I created a 3D printer file with, at the end of the "final code", I entered the M81 command.

Let me to show you what happens:

When the print finished, the relay open the circuits and the printer shut down.

In the same time the led turn on.

When i press the button next to the led, the printer will turns on.
