The filament sensing docs (https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_filament) say: "For all firmware versions, note that filament monitoring in RRF is only active when printing from SD card." We are using an E3D Toolchanger controlled by DWC. Would we be able to add filament sensors and still use DWC, or would we be forced to print from SD cards?
