F-Engrave

Release Notes: This release adds an option for b-carving or ball-carving (analogous to v-carving with a round nose tool). Options have also been added for disabling the use of g-code variables (for expanded g-code interpreter compatibility) and limiting the maximum cut depth for v-carving. The default behavior of v-carve step size has been modified to default to reasonable values when switching between unit types to ensure metric users will start with a good default step size.

Release Notes: Support for DXF polyline entity "bulges" was added. The code was modified for compatibility with Python 3 (Python 2.5 through 3.3 is supported). Stale references to the grid geometry manager were removed, fixing a compatibility issue.

Release Notes: This release enables use of non-English characters, adds g-code generation for cleaning islands and adjacent areas of v-carvings, and adds an arc fitting to g-code output. A couple of GUI bugs introduced in 0.8 have been fixed.

Release Notes: This release includes interface updates for working with image (DXF or PBM) files and adds post processing logic to reduce rapid move distance and frequency. Additional changes include a fix to allow importing some DXF files and miscellaneous user interface changes.

Release Notes: This release includes speed improvements to the v-carving algorithm (up to 20 times faster) and eliminates the issue of F-Engrave appearing to freeze during v-carve calculations. Also included is a v-carve calculation status (percent complete, time remaining, and total time) and a "Stop Calculation" button to terminate v-carve calculation without exiting the F-Engrave.
