This page documents Ultimaker #2 (Fawkes) [A phoenix from the ashes]


  • The Ultimaker is in working order.
  • Uses 3mm PLA filament.
  • It is managed and accessible from the web GUI: http://octopi2.hacklab.to/

Machine Log

Date Notes Entry By
September 26, 2015 Removed overly-brittle, broken PLA from the feeding tube. Machine back in working order with new PLA. PLA can become stale and brittle due to moisture absorption. Justin
July 28, 2013 Found new Arduino mega and installed marlin firmware via CURA. Checked all axis movements, checked thermocouple via external temperature sensors and finalized hot-end. Installed build platform. Removed raspberry pi. Norm
July 27, 2013 Cemented thermocouple into tube, fit tube into hot end. Attempted firmware uploads using Cura (failed) and Xloader (succeeded) Norm
June 23, 2013 Machined remaining parts and assembled feeder, mounted and tested (dry run without power, tensioner only).

Attached flying lead ends of thermocouple onto thermocouple amp.
Wired in thermocouple amp, wired in feeder wiring.

June 22, 2013 Printed out and assembled most of the feeder, lubricated gantry. Norm
June 18, 2013 Printed out parts for feeder Norm
June 10, 2013 Stripped apart old filament feeder and began building new feeder which uses the hobbed pulley. Parts on order, machined other parts. Norm
June 8, 2013 Rebuilt hot-end, rebuilt gantry components, mounted entire gantry, roughly aligned belts, verified general mechanical functions!

Finished mounts for build platform (cutting build platform and mounting to be completed).

May 29, 2013 Boden tube, V2 hot end components, and belts arrived. Norm
May 16, 2013 Ordered Boden tube and V2 hot end components (the feeder upgrade can be printed for cheap). Belts ordered for Ultimaker 1 (when they are needed for replacement). (~$138) Norm
May 15, 2013 Printed Z home switch adjustment block and holder.

Designed and printed parts for new build platform system.
Disassembled Z axis, examined and attempted to straighten leadscrew (limited success), inserted main portion of the build platform innards.

April 29, 2013 Printed fourth X/Y bushing block and Raspberry Pi bracket Norm
April 27, 2013 Assembled 3/4 X/Y bushing blocks, 4th print failed mid-print. Norm
April 24, 2013 Unmounted dual extruder.

Stripped out X/Y gantry parts for rebuild (X/Y blocks broken).
Observed Z acme rod bent.
Remounted Arduino Mega and driver board.

April 22, 2013 Reorganized shelf to accommodate the Ultimaker, organized materials and supplies. Norm
