I have used my MPCNC with my SKR Pro board for a while now without problems running marlin 184.108.40.206.
Today I decided to update the firmware to 220.127.116.11.
I am using some custom menu items which run M42 commands to switch relays on and off. It always worked fine, untill today.
When I boot up my MPCNC and run the M42 command for the first time, it does nothing.
I have to run M42 P112 S255, then M42 P112 S0 (still nothing happens) and after that I can finally use the commands like they are supposed to.
Does anyone know what might cause this weird behaviour? It has always worked fine.
Thank in advance.
PS I will also ask on the Marlin GitHub
