This describes the current progress of the building of the Makerbot. Instructions are found here, and a forum for it is found here.

Noisebridge's Makerbot kit, thoughtfully purchased by Mitch, arrived at 83C on Monday evening, July 20. Leading the assembly team is Joachim, along with Christoph, Rachel, Steve (Mr Domino), and Jeffrey (ieatlint).

It took about an hour and a half to go through and check the parts against the parts list. We think we are missing a bag of "laser cut pulleys" but it's hard to be completely sure, as there are a LOT of parts and they are not all labeled exactly as in the parts list A bag of "laser cut pulleys" was replaced by MakerBot-made pulleys, but the parts lists weren't updated. We determined to start assembly anyway.

Cupcake Electronics Assembly

Instructions Christoph soldering one of the stepper motor drivers, one of the endstop switches, and the SMD parts on the motherboard with only occasional bitching to people to STOP MOVING THE TABLE.

Motherboard is tested and able to control stepper motors. Regular firmware needs to be flashed back onto it. This may help. Ieatlint 02:55, 25 July 2009 (PDT)

Cupcake Pulley Assembly


Cupcake CNC Body Assembly

We got the first part of the body together without difficulty, but had trouble with the Z stage as one of the parts had changed from when the docs were written. The Z stage rod holding guides changed from being O-shaped to being U-shaped, and are marked "Z guides". The forums told us to use them anyway.

The next problem was with threaded rods, which had been cut to size. The ends of some would not take a nut. We solved this with judicious use of the bench grinder. There were LOTS of nut/rod jokes, and we were in a state where they were actually funny! Rachel 10:08, 21 July 2009 (PDT)

Progressed to and including the step entitled "Z-stage stepper wiring" as detailed on the body assembly instructions. The body assembly is nearly completed. Ieatlint 03:52, 21 July 2009 (PDT)

Cupcake Y Stage Assembly


Cupcake X Stage Assembly


Plastruder MK3 Assembly


  • Note: Ubuntu 9.04 specific: the and the RXTXcomm.jar that come in the replicatorg download need to be replaced with some binaries from this other place that I don't remember. -Skory
  • Progressed through to end of Heater Barrel Assembly. Miloh 04:24, 21 July 2009 (PDT)
  • Progressed through the Filament Drive Assembly, and Joachim mastered the extruder electronics. Miloh 02:03, 24 July 2009 (PDT)
  • Progressed through Attach Heater barrel through step 3. Miloh 13:17, 24 July 2009 (PDT)
  • Progressed through Attach Heater barrel to the end. Miloh 20:46, 26 July 2009 (PDT)
Continue at Plastruder burn in test.  The burn in test can't be completed until the Thermistor and extruder board are recognized by the control system.
