The flow sensor cable pack is a critical data link for the UltiMaker S-series "Pro Bundle" ecosystem. These cables transmit real-time data from the filament flow sensors located within the feeders back to the printer's mainboard. This feedback loop is what allows the printer to detect filament run-out, friction spikes, or path blockages. Because the S-series feeders are mounted on the rear of the machine, these cables must be of a precise length to ensure a secure, tension-free connection while routed through the internal chassis channels.
If your printer is reporting intermittent "Filament not detected" errors, or if the flow sensor fails to trigger a pause when a spool runs dry, the internal copper strands within these cables may have become fatigued or the connectors damaged. Replacing the cables with this genuine pack ensures that your industrial safety features—like the auto-pause function—remain 100% reliable during high-stakes, long-duration prints.
This cable pack is the official service part for the following large-format models:
