Using 1.75 mm filament in Ultimaker

Recommended Posts

I purchased a PTFE ID2 OD3 tube from ebay and slid it inside the original PTFE tube. The newer feeder rig does not give enough pressure for 1.75 mm filament, so I had to remount the original Delrin plate. Even with the old plate the filament will start slipping at moderate speeds (100 mm/s) and I have to print slowly (50 mm/s).

What kind of speeds are you other 1.75 mm users getting?

Are there any extruders or feeders that are more suitable for small diameter filament? Is there a dual hobbed bolt arrangement? (it would grip both sides)
