Auto off printer module universal.

A printer that remains in standby consume about 30w, install an auto_off can prove advantageous
I give the procedure for RAISE3D 3D printers

M81 - Power off: pin 45: 1

This order order did not allow me to make a functional module

In this way, it is not possible to operate the stop (PS_ON), ​​when the stop occurs the pin 45 returns to 0, the machine restarts.

So to solve this problem it is necessary to invert the levels of the gcode commands
