It's been a few months since your post, did you ever move forward on your upgrade?

I'm also frustrated with my machine.  I seem to be spending more time calibrating instead of printing.  I've been considering doing a full upgrade/mod  (hot end, extruder, build platform, auto bed leveling). But by that point it's almost an entirely new machine.  Maybe I should just start from scratch.  In either case, this looks like an awesome extruder with the E3D hot end: https://www.matterhackers.com/store/printer-accessories/e3d-titan-aero-extruder-12v-300mm

The configuration looks like a good match for our x-carriage (horizontal rather than a vertical Prusa-type platform).

Thanks for the info!

General 3D Printing Talk / Changing Filaments
« on: March 13, 2014, 04:10:22 AM »
I just finished building my Bukobot, have ran through the test flight and have done the initial test print (bed perimeter and 3 cylinders, etc).  I have been using the sample PLA filament that came with the kit, but now I want to switch to another color filament.

I found a youtube video that describes the process as such: (https://www.youtube.com/watch?v=cKhdUj3f0UI)
  • Loosen/remove the filament tension
  • Heat the extruder to about 100d
  • When the temp gets to about 80 degrees pull the filament out

I tried it, but the amount of force that I used didn't work and I was reluctant to use more in fear of damaging it. 

On the Bukobot, what's is the proper way to extract the filament and install another? 

If this is documented someplace, a link would be greatly appreciated.
