Pause when external sensor sends signal

[mkcommedj 0]

Hello guys!

I am creating a Security tool to avoid crapy print. Indeed, if your material spool is not rolled correctly, that can be stock behing your UM2. In this case, the print carries on but nothing comes out from extruuder because the filament is stuck somewhere behind.

So I decided to invent something cool, very cool. This is nothing more than a switch: when filament is running around spool, switch is pushed on. If stuck somewhere, filament is stoppep, then the switch goes off.

I just need the code and the port on the UM2 to say "if switch = off state, then PAUSE" something like this

Can someone help me please?
