My Solidoodle 2 system has all Ball Bearings on the Filament supports, and there is no noticable wear on the extruder &amp; no filament stripping. I even soak my Ball Bearings in Synthetic engine Oil, to further reduce the friction.</p><img src="https://community.element14.com/aggbug?PostID=3305&AppID=197&AppType=Weblog&ContentType=0" width="1" height="1">RE: 3D Printer Filament Automatic Dispenser for Arduino - #1 Design and Hardwarehttps://community.element14.com/challenges-projects/project14/open-arduino/b/blog/posts/3d-printer-filament-automatic-dispenser-for-arduino---1-design-and-hardwareMon, 17 Jul 2017 21:56:29 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:024b88c4-280d-48a0-8ee7-0ec83177fbffbalearicdynamics0<p>Thank you.
