Printer settings
- Download the replicatorg below to an OSX or Linux box and extract it using the following command:
- tar -xf replicatorg-0025-lvl1.tar.gz
- Run replicatorg:
- cd replicatorg-0025-lvl1
- ./replicatorg
- Open an STL file
- Click Move
- Set on platform
- Center
- Click Generate G-Code
- Select type of plastic you're using
- If it's not slightly clear, you're probably using ABS
- The non abs settings have not been tested and might not work.
- Once g-code generation is done you're ready to print! (I'll write those instructions later)

Modifications
- Z axis crank http://www.thingiverse.com/thing:975
- Y axis belt tensioner http://www.thingiverse.com/thing:1618
- Z axis wobble arrester http://www.thingiverse.com/thing:3057
Working on it
- Z axis wobble
- http://www.thingiverse.com/thing:2151
- everything is printed and shafts are in
- parts are installed needs to be tweaked
- Automated Build platform belt wobbles
- I have no idea maybe a new belt made of thick kapton tape built to a tighter tolerance. covering it with pieces of narrow kapton seems to work for now.
Known Problems
extruder motor seizedFixed with http://wiki.makerbot.com/the-great-motor-mysteryPower supply diedreplaced with RMA- Z axis wobble It will die
- Automated Build platform belt wobbles allowing print to move -- this part has been removed until a suitable solution can be devised
Future Ideas
- Print wireless using bluetooth http://wiki.makerbot.com/bluetooth-communication
- Making our own filament http://hackaday.com/2010/08/05/recyclebot-digests-milk-jugs-to-feed-makerbot/
