There was an issue with a unknown character in a comment tag 😎
I tested the script now, and because I’m lucky enough to have the old board with the real buttons:
It is now sending the can-message each 100ms (while pressed) (S1 sends the 470 and S2 sends the 351 message).
Posted a demo on YouTube;
I’ll mail you the test plugin, *very curious whether it will switch your RNS-E to REV-Cam :)*
