Does anyone know where the two relay control wires should be attached to the RAMPS board?

I'm guessing not D08 terminals used to power the smaller heat bed on my other printer.

Thanks

If you have dual extruders, you can put it instead of the cooling fan, but you'll lose the fan capability and have to use a fan extender to get it back.

If you only have a single extruder, you should have a free port in the screw terminal region there.

Either way, you will have to make 1 or a few small changes in the firmware Configuration.h file.

Remember to put a diode across the relay terminals backwards to prevent electromechanical blowback!
