I have my ports and pins set up.
Under ports and pins enabled pin 1 at port 1 enabled high
I get 4.5 volts out at output 1 (pin 1) with M03 and 0 volts with M05
with no load.
So the pin 1 works. I just can't get it to trip a 5 volt relay. I have tried
a 3 volt relay, a sold state relay ans an optoisolator and can't get to trip.
My outputs to the three drives works fine and the control runs programs.
My E-Stop input works fine. I tried different outputs, pins 2 and 3 and
can't get them to work.
Thanks if anyone can give me advice.
