AllHandsActive has two Makerbot Industries Cupcake series 3D Printers. The printers are both heavily modified from their original state so aside from the chasis saying Cupcake, refer to documentation shown below.

3D Printer workstation

About

A small netbook (host name: FLICKY) sits with the 3D printers. Use the 'AHA' login with the usual back room password. ReplicatorG and Slic3r are installed and configured. It has an SD card slot so you can also use it to build to card and print from that.

_Unplug_ and shut down when not using it.

Feel free to use the netbook and take it along when you transport printers.

Known issues

Replicatorg loads full screen, right click on program in XFCE top bar and say always on top, this will then put the window in the right place and allow you to resize. Alternatively attach a larger monitor.

Creamcheese Cupcake

This bots history

This machine started as a Cupcake with Gen3 electronics and Gen3 Extruder.

  • 6/10 - Bot recieved
  • 7/10 - Changed to makergear hot end
  • 1/11 - The X and Y axis were made a low rider and changed to be quiet and more accurate.
  • 5/12 - The DC extruder died during a 3D printing talk at Penguicon 2012. Switched to Stepper extruder
  • 7/12 - Replaced stepper drivers with Pololu
  • 10/12 - Accelerated

Things this bot has:

What do I need to run Creamcheese? (UPDATED 10/4!)

  • Get ReplicatorG 0039 Sailfish edition (MUST BE THIS VERSION!) - Sailfish Replicatorg/
  • Get Slic3r 0.9.3
  • Get the Creamcheese config files from here: Tyler's repository of cool stuff! - UPDATED 8/* (THESE ARE NOT YET PUBLISHED AS OF 10/4 AM!)
  • Put the *.xml files in your replicatorg machines directory
  • Load the config.ini file into slic3r.

Printing with Slic3r and Replicatorg

  • Get a model in STL format ([Thingiverse.com] or cad program)
  • Start Slic3r and make sure Creamcheese settings are loaded
  • Under Print Settings, change fill density and shells. We recommend .30 fill density and 2-3 shells.
  • Under platter drag your STL files into slic3r or use the Add button. Move things so they will fit.
  • Press export GCode.
  • Open ReplicatorG and connect to CreamCheese with machine type CreamCheese - Slic3r (supported)
  • File->Open and pick your newly generated GCode file
  • Pick build to file
  • Save the resulting .s3g to an SD card with a filename no longer than 7 character.
  • Put the SD card in the bot
  • In ReplicatorG open tools->control panel.
  • Preheat the bot to 220 and the platform to 110. When it reaches temp turn on the extruder until plastic comes out.
  • Clear nozzle and lower to center of platform only a very tiny bit above it. You can use the controls in the control panel to do this or manually move it.
  • Close control panel and pick build from file.
  • Choose your .s3g file from the list.
  • If print doesn't stick at start, hit cancel, clean platform and try again.
  • After finish let print cool on platform. When cool the print should remove easily without deforming.

FAQ

  • What happened to Skeinforge/Why do I need Slic3r? It was much easier to get good prints from Slic3r and generating Gcode is faster. ReplicatorG doesn't have great documentation but we provide files you can use to set it up for non-accelerated prints. In theory all you need to do is change the feed rates to something higher with acceleration but it didn't produce good prints.
  • Why can I no longer print over the USB cable/Why should I use the SD Card? We added the 1/16th step drivers and it creates a lot of traffic that the USB cable link can't handle for parts with lots of little tight corners. You can still print over USB for smaller objects if you want. Try it! If your print pauses and has blobs use the SD Card instead. Another advantage is if your computer dies or sleeps the printer will keep working via SD Card.
  • But a USB cable is super fast! What gives? The USB cable looks like a USB cable, but it is really a USB to Serial cable. The makerbot talks to the computer over serial and that is significantly slower than the USB maximum.
  • My print didn't work. It said it printed but it did nothing. What did I do wrong? Make sure you used a short file name when making the S3G file. Long file names cause the bot to do this.

BlackBottom Cupcake

This bots history

This machine started as a Cupcake with Gen3 electronics and Gen5 Extruder. The DC extruder was upgraded by Ox to a Gen5/6+ stepstruder. The bot originally was given a 3G5D board but it never worked well. As a result we did the ugly cable hack.

At some point Ox decided to donate this bot to AHA!

It was renamed from Ox's bot to BlackBottom Cupcake (alternate name for a creamcheese cupcake) on 7/1/12

Things this bot has:

  • Gen3 Electronics + Gen4 stepper for extruder
  • Mk6 Stepstruder
  • Acrylic Platform
  • .40MM Nozzle
  • RobG's 3G5D firmware.

How Do I run BlackBottom Cupcake?

Printer currently broken: Firmware needs to be updated to Sailfish and documentation updated. If you need to 3D print something in the meanwhile, you should use Creamcheese.

Once you have the bot configured, but before printing.... move the nozzle up and run the extruder manually from ReplicatorG to ensure it is feeding properly. This only needs to be done for the first print or after changing colors.

  • Get ReplicatorG 0029 R2 (MUST BE THIS VERSION NOT NEWER!) - Google Code Listing
  • Get the Creamcheese config files from here: Tyler's repository of cool stuff! - UPDATED 7/2
  • Put the *.xml files in your replicatorg machines directory
  • Put the folders (ex. SF40-BlackBottom-Cupcake-3mm-.35SD) folders in your sf_40_profiles folder.
    • On linux this is in a hidden home folder directory (ex: /home/worman/.replicatorg/sf_40_profiles
    • On Windows this is approximately: "\replicatorg-0029_r2\skein_engines\skeinforge-40\skeinforge_application\prefs\"
  • Start up replicatorg and pick machine type of BlackBottom Cupcake 3G5D (RPM)
  • Save .s3g file to an SD card (or usb stick and then transfer to SD on the mini computer.) Be sure to use 16 CHARACTERS OR LESS in the file name!!!!
  • Put SD card in bot (while it's off or on, doesn't seem to matter).
  • In replicatorG tell it to build from file and pick the file from the list.
  • Watch it go...

The Replicator

This Bots History

This bot was won by Backyard Brains and is for their use only. If you need to use it, contact a member of their staff or Tyler to setup a job for you.

How do I run the Replicator?

  • Grab the latest version of Replicatorg.
  • Slice using the Replicator Profile for the latest version of Skeinforge for the left or right extruder.
  • Build to SD Card
  • SD card into replicator
  • In replicator menu, level the platform
  • Preheat the head you wish to use.
  • Select file from SD Card.

If the Kapton tape is ripping, reapply two new pieces from the roll and smooth them as you put them on. It is best for the bed to be cold when you do this.
