The Makerbot Cupcake CNCs from batch 6 came with a laser cut [http://wiki.makerbot.com/plastruder-mk4 Plastruder MK4]. To drive the filament a T2.5 timing belt gear was used, it had 17 teeth which would bite into the filament, however the teeth were blunt so could not get a good grip on the filament reliably. This lead to the extruder jamming mid way through a print. When the Plastruder MK4 came out it was a new design but it was quickly superseded by improvements from the RepRap project. | The Makerbot Cupcake CNCs from batch 6 came with a laser cut [http://wiki.makerbot.com/plastruder-mk4 Plastruder MK4].
