`Inset is a script to inset the carvings of an svg file.
Inset insets the svg slices into gcode extrusion layers. The 'Extrusion Perimeter Width over Thickness' ratio is the ratio of the
extrusion perimeter width over the layer thickness. The higher the value the more the perimeter will be inset, the default is 1.8.
The 'Infill Perimeter Overlap' ratio is the amount the infill overlaps the perimeter over the extrusion width. The higher the value the
more the infill will overlap the perimeter, and the thicker join between the infill and the perimeter. If the value is too high, the join will
be so thick that the nozzle will run plow through the join below making a mess, the default is 0.05. There are two choices for the
infill perimeter overlap method of calculation. If the 'Calculate Overlap from Perimeter and Infill' option is chosen, the overlap will be
calculated from the average of the perimeter width and the infill width, this is the default choice. If the 'Calculate Overlap from
Perimeter Only' option is chosen, the overlap will be calculated from the perimeter width only.
If the "Start at Home" preference is selected, the G28 gcode will be added at the beginning of the file, the default is off
When inset is generating the code, if there is a file start.txt, it will add that to the very beginning of the gcode. After it has added some
initialization code and just before it adds the extrusion gcode, it will add the file endofthebeginning.txt if it exists. At the very end, it will
add the file end.txt if it exists. Carve does not care if the text file names are capitalized, but some file systems do not handle file name
cases properly, so to be on the safe side you should give them lower case names. It will first look for the file in the same directory as
inset, if it does not find it it will look in ~/.skeinforge/gcode_scripts.
The following examples inset the files Screw Holder Bottom.gcode & Screw Holder Bottom.stl. The examples are run in a terminal in
the folder which contains Screw Holder Bottom.stl and inset.py.
> python inset.py
This brings up the dialog, after clicking 'Inset', the following is printed:
File Screw Holder Bottom.stl is being chain insetted.
The insetted file is saved as Screw Holder Bottom_inset.gcode
