using the leftover GPIOs to switch on relays

Hi

I am trying to come up with the simplest way to command relays with the gpio pins that are not in use for the HAT. The sweetest possibility would probably be custom M codes that would then change the state of a given pin but I have 0 coding skills and would need something to copypaste to get this done. Anybody did it already and would be interested in sharing the lines?

Is there any other way to automate the mill a bit more? basically I´m looking into automated stock loading and later an ATC.

Thanks!
