The hardware is in place, and some cura profiles are available to download. Please make sure to set the bed size correctly in the cura preferences. (also confirm steps_per_E is correct.) The extruder clogs easy, and isn't very adjustable right now.
Done. The cupcake is now as usable as the ultimakers. (Same software workflow.) - Print quality is not as high, but sufficient for mechanical parts.


Otherwise, the printer is usable in its current state. Printrun is available on the connected raspi.

Cupcake Refurb Project 2013

From June to August 2013, a number of major upgrades have been performed to make the cupcake more useful and relevent.

Status

Done. The cupcake is now as usable as the ultimakers. (Same software workflow.) - Print quality is not as high, but sufficient for mechanical parts.

Completed Work

  • X,Y mendel style with 10 bearings/axis [ http://www.thingiverse.com/thing:3697] [1]- PLA printed Y part cracked, only 9 bearings installed. Still runs well.
  • Wade's extruder for cupcake [2]
    • Hobbed bolt + gear from ultimaker spares
    • Stepper based extruder - stepper borrowed from ultimaker.
  • Old Ultimaker (ramps-like) board with arduino Mega that has to be returned to Fumon - Sen to provide alternative?
  • X,Y endstops implemented with random mechanical switches found around the lab.
  • Tuning: X,Y,Z Steps_per_unit
  • Raspi configured with arch and printrun.
  • Extruder tuned, replaced gear with 3d printed one (was using old wood ultimaker gear, now using same type of gear as the ultimaker.)
  • took apart, cleaned out the makergear extruder.
  • Toolchain integration (Cura profile/prontserv) - Note: Cura preferences must be altered to match machine dimentions.
  • Z endstops
  • Wiring and connecting ABP.
  • Cura plugin for ABP at end of print
  • Power status LED (Thanks Sen!)
  • LED Strip - Regulator runs hot though, usually unpluged.
  • Z Axis replacement - [3]
  • Crappy Bed leveler

Todo / WIP

  • Need a bed leveler design which doesn't add wobble to prints
  • ABP tends to be a bit wavvy. Investigate paper/kapton option or metal foil for replacement belt.

Parameters and notes

  • Using Marlin firmware. Full configuration to be posted on github once it's more stable.
  • Motor model: KYSAN SKU: 1123029. Using 12V, 0.4A. (xyz only, extruder = better motor.) - Set pololu ref voltage to a bit under 0.16v.) [4]
  • PID values + thermo values being played with. Default values overshoot hotend significantly.
    • See reference values here: [5]

Historical

The Hacklab has made a number of customization to our Makerbot:

  • Thermocouple in the Plastruder heater instead of the default thermocouple (including adding converter board for signal)
  • Heated build platform
