Ultimaker 2

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

Ultimaker #2, also known as "Fawkes"

Printer lives on the third shelf of the 3D printer tower, next to the Type A.

Status

• DOWN ... needs service
  • Filament Feed teeth need to be cleaned
  • then Zero Stop needs to be ajusted.
• When this is Operational ... it can be Problematic
  • Bed Level and/or Zero Stop will go out of adjustment, during a print.
  • This causes print head to be too close to bed when starting next print.
  • If head too close & extruder starts clicking, filament feed gear clogs with plastic.
• Loaded with Turquoise 3mm PLA
  • This is old PLA ... so try using 220° @ 110% flow
• PLA ONLY! (to prevent nozzle contamination)
• Cura 15 Settings here
• http://octopi2.hacklab.to/

Features

• Ultimaker Original with extruder drive upgrade
• Built from an incomplete kit and a bunch of parts are 3D printed
• 210 x 210 x 205 mm print volume
• 2.85mm filament
• Absolute max temperature: 250 C
• It is managed and accessible from the web GUI: http://octopi2.hacklab.to/

Machine Log

Date	Notes	Entry By
March 9, 2017	The Print Head Fan Duct was touching the build plate before the front/right corner was down enough to be level. Used a fine file to trim the underside of this 3D printed part, so this now stays just slightly above the build plate at all times.	Allen
March 1, 2017	X axis just stopped working mid-print again. Re-seated x axis stepper board again, and this time used Kapton Tape to secure all the the stepper board DIPs in place.	Allen
February 28, 2017	Lubricate X-Axis rods using NCR Silicone Fluid. X-Axis now moves back & forth smoothly. (Left side of belt no longer bends sideways @ the stepper motor.) Hardened/old lubricant on the X-axis rods also removed by doing this.	Allen
February 21, 2017	Igor helped to locate & fix bad driver board (DIP socket) connections for the X axis stepper motor. Removed broken PLA from feeding tube (yet again). The working PLA reel from Ultimaker 1 was moved to this unit.	Allen
Mid-2016	Re-printed extruder drive tensioner in ABS on Ultimaker 1, replaced Bowden tube coupler springs. Snipped 1cm off the tube ends to give couplers fresh surface to hold on to.	Igor
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.	Norm
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).	Norm
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.	Norm
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.	Norm
April 22, 2013	Reorganized shelf to accommodate the Ultimaker, organized materials and supplies.	Norm
