28 Feb How to spool a perfect filament with Felfil Spooler

Have you ever wondered how to create the perfect filament? This article is for you!

Our system is composed by three equipment: Felfil Shredder, Felfil Evo, the extruder and Felfil Spooler that it is able to spool and calibrate your filament. 

Our spooling system is equipped with a filament diameter control system, and will guarantee a constant filament thickness and will automatically calibrate your filament.

Felfil Spooler includes presets for the most common material, but it can also be used in custom mode for experimental materials. 

The distribution allows to share the filament and the clutch does not stretch it; four fans, whose airflow is adjustable, cool down the filament before misure it.

We included a slipper clutch inside the spool in order to allow the filament to be collected on the spool without being stretched.

When it works properly you’ll be able to stop the spool holder applying a small force with your finger without affecting the motor shaft, which will continue to spin freely.

What do you have to do if Felfil Spooler doesn’t work?

If you are noticing an unexpected behaviour from the spool holder probably the clutch is not properly set.
The following procedure will guide you in the slipper clutch setting.

Too tight clutch

If the clutch is too tight the stepper motor’s shaft will not be able to rotate (while turned on) when you stop the spool holder (the black plastic part), and you’ll see the motor shaking in both directions.

In this case you have to unscrew the bolt a little bit in front of the spool holder. 

In order to do that use an allen and a wrench. Keep the shaft locked with the allen then make half of turn with the wrench unscrewing it, then turn on the spooler and check if the shaft is now free to rotate. 

Too loose clutch

If the filament can’t be collected on the spool, but the spool is actually spinning, the clutch is probably too loose. 

You have to tight it, since it need to be hard enough to bend the filament, keeping the shaft free to rotate.

In order to do that use an allen and a wrench. Keep the shaft locked with the allen then make half of turn with the wrench screwing it, then turn on the spooler and check if the shaft is now free to rotate.
