Since this is my first post here, Hello to everyone.

As the title implies I would like to switch a relay using the ActivateSignal command.

I can switch the relay by clicking the active low button in the output tab. So the wiring seems to be ok.

So far I didn’t manage to switch the output by using the ActivateSignal command.

I setup Output #1 on Port 1 Pin 8

As far as I understood the code should be

ActivateSignal(OUTPUT1)

I put this in a M999 script and called it via MDI. The relay doesn’t move, but the Stepper Motors move a bit each time I call the M999.

What is going on here?

Solved: Turned out to be a week power supply on 12v.
Strange though that it worked in the Output Tab but not with the ActivateSignal command.
Anyway, with a separate power supply for the relay it works also with the script command now.

 

Pleased you found the problem.
