Fillet is a script to fillet or bevel the corners on a gcode file.
The default 'Activate Fillet' checkbox is on. When it is on, the functions described below will work, when it is off, the functions
will not be called.
Fillet rounds the corners slightly in a variety of ways. This is to reduce corner blobbing and sudden extruder acceleration.
The 'Arc Point' method fillets the corners with an arc using the gcode point form. The 'Arc Radius' method fillets with an arc
using the gcode radius form. The 'Arc Segment' method fillets corners with an arc composed of several segments. The
'Bevel' method bevels each corner. The default radio button choice is 'Bevel'.
The 'Corner Feedrate over Operating Feedrate' is the ratio of the feedrate in corners over the operating feedrate. With a high
value the extruder will move quickly in corners, accelerating quickly and leaving a thin extrusion. With a low value, the
extruder will move slowly in corners, accelerating gently and leaving a thick extrusion. The default value is 1.0. The 'Fillet
Radius over Extrusion Width' ratio determines how much wide the fillet will be, the default is 0.35. The 'Reversal Slowdown
over Extrusion Width' ratio determines how far before a path reversal the extruder will slow down. Some tools, like nozzle
wipe, double back the path of the extruder and this option will add a slowdown point in that path so there won't be a sudden
jerk at the end of the path. The default value is 0.5 and if the value is less than 0.1 a slowdown will not be added. If
'Use Intermediate Feedrate in Corners' is chosen, the feedrate entering the corner will be the average of the old feedrate and
the new feedrate, the default is true. To run fillet, in a shell in the folder which fillet is in type:
> python fillet.py
The following examples fillet the files Hollow Square.gcode & Hollow Square.gts. The examples are run in a terminal in the folder
which contains Hollow Square.gcode, Hollow Square.gts and fillet.py. The fillet function executes the preferred fillet type, which
can be set in the dialog or by changing the preferences file 'fillet.csv' with a text editor or a spreadsheet program set to separate
tabs. The functions writeOutput and getFilletChainGcode check to see if the text has been combed, if not they call the
getOozebaneChainGcode in oozebane.py to fill the text; once they have the oozebaned text, then they fillet.
> python fillet.py
This brings up the dialog, after clicking 'Fillet', the following is printed:
File Hollow Square.gts is being chain filleted.
The filleted file is saved as Hollow Square_fillet.gcode
