Filament Jam Detection

On any of your printers, I think it would be trivial to add an encoder onto the bowden tube input (where the filament is located) in order to "count" the forward and backward movement of the filament coming off of the spool. This could also be utilized for a runnout sensor for future iterations, but if the filament is not unwinding after X number of movements calling for plastic feed, it would be safe to assume that a jam has occurred and to pause the print. If your team would like more information as to what I mean by this, please let me know and I can make a diagram.

This is an interesting idea, I'd support it.

That would be a useful feature for the cloud!

I also wish it was an option to set unload and certain temp if it detect a clog.

So if it detect that the filament is not loading while printing it could move the head to the side and unload filament while set nozzle temp to a value for the filament you are using. So petg it could have a temp around glass temp so it stay soft but not burning. Or have the option to set 0c.
This could be set in the menu on the machine so when you load/unload and choose filament type and temp it could have a clog detection temp and behaviour.
