Are there any G/M codes that will work as a wait timer, I want to hook up an i/o device and have M3 pause until i activate an external signal, then progress through the rest of the program. Think something like this;
G0 X 1.0 Y 1.0
then wait for input pin *********x to see signal, when it does
G0 z -1.0
Also I need to turn on outputs to pick up external devices, I'm thinking modbus or poKeys. Any help/opinions would be appreciated. I'm newbie so be kind.
