UP! Modified Extruder Feeder *No Moving Parts* V2 by Eurisko84 Feb 23, 2012

Description

A re-designed UP! Extruder Feeder/Cable Tray design. Removing the roller bearing and housing and replacing with spring steel guide element. This gives greater flexibility in filament thickness diameter, along with the added simplicity of design. Includes a fitting for air line supply to cool the extruder gear.

Doesn't work... the piece lacks proper filament guide at the bottom and filaments gets bent....

Hi I noticed that the up! Has a unused connector on the pcb of the extruderhead. I was wondering If I could connect a extra fan on this connector (it looks exactly the same as the connector that connects the standard extruder fan. looking at your pictures I saw you connected a extra fan to this free connector. Did you used a normal 12 volt pc fan or a different voltage?

Sorry for the delay - only just got around to fitting v1, which didn't work for me (alignment issues with the pen clip I suspect). I like the fan mounts - my experience has been that keeping the stepper cool is the biggest factor in getting reliable prints

I'll try to find time in the next week or so to try v2

cheers

*UPDATE 03/08/2012*

Version 2 has been released with fittings for two 50mm fans (to suit heatsinks) and adjusted filament outlet and air line positions to minimise mis-feeds.

New files below, and am keeping the originals for those who don't want to add a fan.

Buy an Artline felt pen (this is an Australian brand pen with a steel pocket clip - see here pelikanartline.com.au/index.php?option=com_content_ex&view=category&layout=multi-view&id=69&Itemid=154 )and remove the steel clip from the lid.

Print out, clear all holes and guides and install pen clip as shown. Install onto servo motor, and ensure the clip clears the gear.

Reinstall onto printer, and extrude!

You may need to adjust the size of the outlet guide hole if your spool curls too much (only open it up a little).

This is a prototype design, but has been tested to work with some pretty bad filament!

The clip from a Pilot "Precise V7 Premium Rolling Ball" pen also works. These are readily available in the U.S. from most office supply chains.

Nice looking print! Madox put me onto your post, and I can't wait to try it on my up as well.

Come check us out at Robots and Dinosaurs sometime. I think you'd fit in nicely!

Nice! Will try it out this weekend

From your thread I see you are in Sydney, you might like to check out robodino.org - there's numerous Up! owners that I suspect wil be interested in your design
