Fillet rounds the corners slightly in a variety of ways. This is to reduce corner blobbing and sudden extruder acceleration.

Operation


The default 'Activate Fillet' checkbox is off. When it is on, the functions described below will work, when it is off, the functions will not be called.

Settings


Fillet Procedure Choice

Default is 'Bevel''.

Arc Point

When selected, the corners will be filleted with an arc using the gcode point form.

Arc Radius

When selected, the corners will be filleted with an arc using the gcode radius form.

Arc Segment

When selected, the corners will be filleted with an arc composed of several segments.

Bevel

When selected, the corners will be beveled.

Corner Feed Rate over Operating Feed Rate

Default is one.

Defines the ratio of the feed rate in corners over the operating feed rate. 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.

Fillet Radius over Perimeter Width

Default is 0.35.

Defines the width of the fillet.

Reversal Slowdown over Perimeter Width

Default is 0.5.

Defines 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. If the value is less than 0.1 a slowdown will not be added.

Use Intermediate Feed Rate in Corners

Default is on.

When selected, the feed rate entering the corner will be the average of the old feed rate and the new feed rate.

Examples


The following examples fillet the file Screw Holder Bottom.stl. The examples are run in a terminal in the folder which contains Screw Holder Bottom.stl and fillet.py.


> python fillet.py
This brings up the fillet dialog.


> python fillet.py Screw Holder Bottom.stl
