Filament with bent ends, tape, glue, or tangles can jam the S1 and stop your print. The cutter stops that before it happens by cutting off the bad part automatically.

❌ Clogs

❌ Skipped reloads

❌ Ground or chewed filament

• Automatic Filament Re-loaders (like the S1)
• Direct-to-extruder Setups
• Many AMS/MMU style units

Even without a reloader/AMS, printers with a runout sensor will pause, giving you a chance fix the problem and resume the print.

🔄 Filament enters the cutter’s tube as it loads into the S1.

⚠️ Bent, taped, glued, or tangled ends gets caught in the inlet tube.

✂️ The tension pulls it down into a hidden blade, which cuts off the bad end before it can jam the S1.

✅ The S1 reloads the next spool and keeps your print running without interruptions.
