I am trying to read all of the filament sensors on my K2 Plus CFS. In particular when I try to load a roll of filament it retracts the full roll then gives an error that it failed to retract. This would suggest to me that one of the sensors is reading Filament. I have found how to read the extruder sensor via fluidd and its clear. However, I have not found a way to read the buffer on the back of the unit or the multiple hub sensors.
Does someone have a list of commands to check each sensor in the path?
