Abstract

The invention relates to an FFF printing system (), the FFF printing system comprising a print head (), a feeder () arranged to feed a filament () into the print head (), and a container () for storing the filament on one or more filament spools (). The system also comprises a prefeeder () arranged to feed the filament from the spools to the feeder (), and a first flexible tube (D) for guiding the filament (). A filament path length measuring device () is arranged to detect a misalignment between the feeder and the prefeeder. Measurement signals are sent to a processing system to correct any misalignment.
