This is the python version of my MakeNBreak script. (See old perl script here: http://wiki.makerbot.com/makenbreak) This program takes a commented skeinforge file and stacks the gcode on top of itself, including a layer floating inbetween to make the parts easy to separate with a razor blade. Many improvements have been done such that you no longer need a file with layer in between. Simply use a commented skeinforge file. I've been experimenting with version 36 so hopefully it works with the up-to-date files as well. Hopefully this helps folks that are printing lots of parts. I had good luck using it on a footed vertex. This is great for multiple simple parts. I've printed a few of the Makerbot Prusa files and always had a failure with that method of stacking STLs. Also this is my first thing written in Python so be gentle with comments:)--Make sure you have python installed (same as if you run skeinforge). If you use Mac or Linux you do, but on windows you'll need to go to python.org.--Choose a part that can be stacked. I've only used ones that are fairly simple.--Comments are used to parse the file from skeinforge, so make sure you have the filename_comment.gcode file that skeinforge produces. The program looks for "()" and "( Extruder off. )" I've only tested this with version 36.--Usage:
