Router Relay on/off backwards

Need help. I wired up a relay turn power on and off to the router. My router turns on and off with the opposite “M” commands.

M3 turns it off
M5 turns it in

Spindle automation is set to “relay_low”
I did play with the dead man switch that cuts power to the shield and router

Any ideas?


Change to relay high in Maslow settings

With those relay boards, some activate with a low voltage and others activate with a high voltage. The wrong signal is getting sent.

That was easy. Thought the low/high was for voltage
