Good Morning to all. Today i could write a brain which enables a green led when g code running, BUT I need a little help from someone who could help me to write a brain which triggers an outpout when i press feedhold on mach3 and than this output would flash the yellow led on my machine stack light. Also another brain for when i click on stop, machine's Red  led active and when reset e-stop clicked red led is flashing.

Thank you in advance

Hi, as an example. Have a look at the one on CS-Labs website. I have it running on my machine without any problems.

Thank you alan, but i don't have this device. I have a pokeys56U

Alan, thank you, for me that was useful link.
especially ip-m type, searched a lot about this and ip-m/s.

Have you assigned the buttons (inputs) and the lights (outputs) in mach3?

You can use OEM triggers for the buttons if you are using a button panel. 

You can use brains or you can use a macropump.

Same goal achieved in the end.

I can't acess the link, i need the answer the OP wanted.

Could LED be used, and which one ?
