Hi, I need some advice here. I have a NANO based GBRL controller on my home built and want to hook up a relay for air assist. I believe it uses the M8 command, but what pin does that output to? Is it pulled down to ground on activation or up to 5V. I have a solid state relay that takes 3 - 32 volts on the input, so I should be able to connect directly to the pin. Any info greatly appreciated.
Relay I have.
