Skeinforge only handles additive fabrication. It won't handle milling for many moons because the todo list seems to grow as fast as I develop Indeed it should be possible to subtract the shape from a box, reverse the z slices and play with offsets, but skeinforge doesn't do this now and probably won't be the best tool for a milling job for a long time if ever. I haven't tried it, but Ralith me

I like your game idea. If you want more graphics, you could use nasa pictures, which are all public domain, at: I suggest that you keep your flat tiles for the background (planet, moon, nebula & asteroid) and reprap only your pieces (ships, torpedoes, etc..) so that you don't keep knocking over the background when moving the pieces. Is your game open source?

The skeinforge gui uses Tkinter. "An Introduction to Tkinter" is at: The documentation for python itself is at: The main module for the skeinforge gui is preferences.py in the skeinforge_utilities folder in skeinforge_tools. The gui is hard coded, there is no gui editor. There is a preferences class in each tool which adds widgets to the dialog window. A typical example is FillPreferences

For handling gcode from other sources, whatever code the Arduino is using to process those commands would be ported over to the preprocessing script. So if the Arduino can handle it now, the script should be able to handle it also. Indeed, the code for each conversion is tiny, but there are many of them. The inch to metric and relative moves were the first that came to mind. Also, one of the

Hi Chris, Wow, wonderful work. Another way of shrinking the Arduino code is to preprocess everything you can, like inch to metric conversion & relative moves. All the Arduino would have to do is line, arc, accelerate & control the extruder. Everything else could be processed beforehand with a script. An example of a preprocessing script is gcode_step in export_plugins in skeinforge.

Jon, I updated the code a while back to fix the almost overlap bug. It created new not fill enough bugs, then I fixed those in the latest version.

Hi Ian, I tried hop out and it's raising the temperature change loop. Is your "Hop over Extrusion Height" greater than zero? The default is one. There is only a temperature delay for when the temperature changes, which only happens on the raft, the first layer and any layers which have support. If this still doesn't work, email me your preferences and object to: perez

A bug in support in raft was fixed, unpause, gcode_step & speed have been added, and the update is attached and in subversion. Unpause is a skeinforge tool to speed up the feedrate to partially compensate for pausing. It is based on Shane's delay compensation in the gcode firmware, as described at: The default is off, the delay should only be compensated with unpause or Shane's firmware p

In raft the temperature change times for all kinds of layers are all the same. Would anyone have an objection if there was only one temperature change time? If there was only one time, the raft window would be smaller and would fit on more screens. Enrique

Support material has been added. I don't know how easily the support material can be removed from the object or if the object will stick correctly to itself because it will have cooled while the support is being added, but at least it's there. If anyone uses support and finds temperature which work well, please send em to me so I can make em the defaults. Thanks to Jon, Marius and Philip a bun

Hi Ian, The base feedrate is inversely proportional to the square of the "Base Layer Height over Extrusion Height" ratio. The feedrate is slowed down so that more plastic is deposited in an area, making the thread higher and wider. The default setting is 2, given a base feedrate of one quarter the feedrate preference.

Hi Wizard23, Is your heated plate hotter in the center than the edges and if so has that been a problem? If it is a problem, you could change the script so that a double loops starts around the outside with the edges close together, then as it gets to center the edges would be slightly wider apart so that there will be more heating at the edges of the plate to compensate for the extra cooling

Hi tofletcher, Your binary format is a great idea! It would indeed mostly or totally fix the segment pausing problem, which is standing in the way of high quality prints.

An example export plugin, indeed the only export plugin, is gcode_small.py. You could conve
