Release notes for 0.5.0 (2011-11-14)

After 10 more days of work, a new release is out!

New features:

  • four new exciting fill patterns (including¬†line)!
  • new algorithm for re-processing layers with dirty geometry, this makes the parser more tolerant
  • start and end gcode is customizable in the GUI too
  • new --retract-lift option to lift Z while doing travel moves
  • new --no-extrusion option to disable E codes
  • new --skirt-height option
  • new --first-layer-height-ratio option
  • new --close-after-slicing for easy integration with external programs
  • new --g0 option to output G0 for fast retractions (experimental)

Improvements:

  • perimeters are extruded at once for each island, saving on travel toolpaths
  • perimeters are extruded using a shortest path search, avoiding unnecessary travel
  • smarter toolpaths for infills with different density
  • multiply was renamed to¬†duplicate
  • infill is now overlapped with perimeters by 15%
  • GUI was rearranged using tabs

Bugfixes:

  • fixed fatal error occuring on Windows
  • infill solid layers even when --fill-density is set to zero
  • membranes were not printed correctly
  • G2/G3 coordinates for experimental arcs were wrong
  • print first layer at Z = 1 * layer height instead of zero
