Information

and another UM2 feeder design.

timelapse & instructions : http://youtu.be/CvMu79ZCd9AThis design is influenced a lot by the designs of |robert| & "Geeks". Thanks for your great work !!!https://www.youmagine.com/designs/alternative-um2-feeder-version-twohttps://www.youmagine.com/designs/extruder-um2-version-2And a big thanks to Ultimaker for the published STEP files I could use to take the measurements from!!update: 30/6/14 > added a little knob for easy spring adjustment (see last picture)update; 2/7, as cor3ys already mentioned in the forum the arms holding the bearing are a bit to short (sorry, I only tested at low speeds...) updated the file. Version nr. 25 of the front and back arm have 2mm increased length.At the same time made a little change for easier installing the m3 x 50mm bolt...

Technical

some M3 bolts I would like to use a long m3x60 hex bolt, but could not find one... took a (non hex) m3 x 50 bolt and placed a normal hexnut on it with "bison lock bond" to make a hexbolt....

Here's an updated link to the ultimaker forum https://community.ultimaker.com/topic/4058-ultimaker2-feeder-system-improvements-and-ideas (not sure what page the original referred to since it doesn't seem to be the same).

I have used this version with different materials and only when I use flexible filament there are problems. Are you willing to give me the CAD file so that I can make some adjustments?

I did not really count, but I probably printed at least 50 hours with it now without any problem.

Works like a charm. Much better than the stock feeder. No more under-extrusion.
