Filament stuck on spool

[Kepoxx 0]

Hello,

I'm using black Ultimaker PLA on the Ulltimaker 3 on feeder No.1.

Although Im using the original material guide, the filament got stuck on the spool three prints in a row. 

How con I prevent that from happening?

You are not being very specific about what you mean by "got stuck on the spool", so I can only guess the filament somehow got tangled (ie: the filament on the spool somehow got wound under the previous winding, instead of over). This can happen if you are not careful about rewinding the spool when you change materials.

 

When the printer fully retracts the material from the bowden tube, you can end up with a "jumble" of filament behind the printer. If you just pull that tight, you can create a "knot" in the spool. That knot can sometimes move along with the unwinding of the spool as you print, but eventually it will get tight and cause a failure to pull material into the printer.

 

Allways keep your spools of filament tought but putting the end of the filament in one of the holes along the brim of the spool, and always carefully rewind the spool after removing it from the printer.
