Poikilos Fork

• Preserve this great program, which adds to the public-licensed 3D printing ecosystem.
• Make better documentation (Recover usable website & wiki information from web.archive.org and bmander's README.markdown) and user self-support path such as a forum.
  • See also Skeinforge on RepRap Forum.
• Make a fancy modern UI.
• Choose a better name.
• Add fancy supports.

• Skeinforge performs better than Cura in some cases. A test print and the claim that Cura is based on an "old fork" of Skeinforge is at: http://reprap-art.blogspot.com/2019/01/whats-better-skeinforge-or-cura-engine.html
  • He uses "Slow Down" for "Cool Type" to avoid wavy layers on narrow pillars and a pointy artifact on the top of the Calibration Temple (he actually mentions thing:10199530 which no longer exists, but the new BrunoBellamy Sep 17, 2015 upload is apparently the same).

• A big reason for the program's demise may be that the website's hard drive crashed and the Wiki was never recovered (and the website had a huge span of downtime).
  • I will see what I can recover from the wayback machine.

• Add G-Code viewer, such as (see ~/git/1.todo/G-Code_viewers_for_Python/ on Poikilos' Linux PC):
  • https://github.com/jonathanwin/yagv
  • https://github.com/FMMT666/yagv-ng
  • https://github.com/poikilos/GCodeViewer (fork of PeachyPrinter/GCodeViewer)
  • https://github.com/dkobozev/tatlin
  • https://github.com/C3Dm/GCodeViewer (matplotlib+numpy)
• Consider PyPy for JIT compiling.
• Add later tweaks--consider forking from indazoo's fork: nophead/Skeinforge50plus "Skeinforge50 (the last release from Enrique) with a few tweaks"
  • Use indazoo's more recent version with more changes: https://github.com/indazoo/Skeinforge50plus (forked from AlexeyKruglov's, which also has several changes)
• Ensure good plugins are included, such as "stretch" (arc compensation) by Enrique Perez: https://blog.pcedev.com/2015/06/02/arc-compensation-reprap/
• Ensure github.com/ahmetcemturan has commits for all versions (compare to http://web.archive.org/web/20160606125233/http://fabmetheus.crsndoo.com/index.php?all=true)

• Revise and re-add parts of bmander's README as necessary: https://github.com/bmander/skeinforge/blob/master/README.markdown

  • http://buildatron.com/facts-sfact
• Implement Veroni supports from https://github.com/poikilos/voronizer
  • wait until a license gets added to upstream voronizer (I requested that).
• Implement automatic model turning for least support using turnit if license gets added (I requested that.)
• Make temperature tower feature: Allow user to merely enter the max and min temperature for the filament).
• Pick a different name (see "Possible Alternate Names" below)
• Import Cura profiles such as https://www.3dprintedtabletop.com/resources/3d-printing-profiles/

Skeinforge50 (the last release from Enrique) with a few tweaks:

• Bug fixes

• DeuxVis and Joost-b improvements to Cool with regard to fan control (see http://forums.reprap.org/read.php?154,149615,245895)

  • turn on fan at beginning
  • do not use fan before layer N
  • set fan maximum speed
  • force fan on bridging layers (requires enabling Inset -> Infill in direction of bridge)
  • maximum layer time time for fan
  • turn on fan at full speed on layers less than N sec
  • when using slow-down, set minimum feed rate

• Theodleif improvement to Skirt plugin to add a "brim" (see http://forums.reprap.org/read.php?1,136147,136147#msg-136147)

  • brim width in number of loops

• Dimension plugin improvements

  • firmware retraction via G10/G11 (e.g. supported by Marlin). If set the retraction speed, distance, and extra restart distance are ignored

• delsydsoftware improvements to Fill plugin (see http://www.thingiverse.com/thing:65624)

  • The ability to disable the top layers of a model for printing out cups, vases, or other hollow objects without deleting lines from gcode manually
  • An automatic solid surface thickness feature, which lets you set the thickness of top, bottom, and overhang surfaces in milimeters, instead of layers. This keeps top and bottom surfaces proportional, even when printing in thin layer heights. It results in much cleaner top and bottom surfaces, even with ridiculously low infill settings and small layer heights.
  • Forcing even/odd top layers. The fill patterns on the top layer of a surface are different, depending on whether there are an even or odd number of solid surface layers. I prefer to see the even layers, which use vertical lines. Odd layers tend to use slanted lines, which print more slowly and can be a bit messier. You can now choose whether you want the final layer to be even or odd.

• You can now determine how much of the object to print using the 'Object printing percentage/layer limit' feature. This lets you print 1 layer of an object, which can be handy for printer calibration. It also lets you print a custom percentage of the object, or a custom number of layers. This feature is disabled by default, and is ignored if you have Disable Top Layers enabled.

• svanteg improvement to Raft plugin for first layer support (see http://forums.reprap.org/read.php?154,350315,350315#msg-350315)
  • support flow rate over operating rate (first layer)
