Marlin Host Action Commands
I'm looking for a good way to implement filament runout detection without having to run extra cables to every printer. I saw host action commands in Marlin. This is supposedly supported in Octoprint and Pronterface, but I don't see anything for Repetier host. Is this supported or are there plans to support it? Has anyone else implemented filament runout sensors in an elegant way (many ways to do this that are messy or just use a GPIO if running a PI which I am not)?
