Keeping Good Company – Part 2

A couple years ago I was flattered to learn that one of my projects was referenced in a TED talk by the guy that invented the Arduino.  Today I learned that one of my designs has been incorporated into spray painting drone by the artist/vandal KATSU.  The project is fully detailed on the Icarus One…

Dogfooding with FreeCAD Path

“Eating your own dog food, also called dogfooding, is a slang term used to reference a scenario in which a company uses its own product to validate the quality and capabilities of the product” I have a whole pile of old Altoid tins that I use to store small screws and such.  The tins had…

Bending & Gluing

About a year ago I bought a standing desk.  The desks are really nice but the options for surfaces are either very basic or expensive. I wanted to do something custom so I bought it without a top.  I had an old top (actually a door) to use in the meantime and started thinking about…

A nifty work-around for HeeksCNC Kurve offset error

HeeksCNC can be finicky about profiles.  Often I’ve found that a sketch which should be easily profiled won’t generate any gcode at all.  When I look in the console, I find an error like this   File “/usr/lib/heekscnc/kurve_funcs.py”, line 247, in profile     raise Exception, “couldn’t offset kurve ” + str(offset_curve) Exception: couldn’t offset…

CAD Is Hard!

I got the chance to speak about FreeCAD at the Osmoces event near Chicago over the weekend.  I had a really good time seeing some of the other presentations and exhibits and just hanging around with some pretty cool people.  In addition to the talk, I also taught a workshop where we got hands-on with the software…

FreeCAD WebGL Export.

This is still early but it’s too cool not to share.  Yorik has added a WebGL exporter to the FreeCAD arch module (but it seems to work everywhere in FreeCAD) Open a model in FreeCAD and select the objects in the tree   Export the objects (File -> Export) and select WebGL     Save…

Vendor provided CAD data.

I’m going to build an enclosure for my CNC mill to keep coolant and chips from going all over the floor. It took about ten minutes to model the mill table in FreeCAD but modeling all the aluminum extrusions was looking like a lot of work.  Fortunately it isn’t necessary More and more vendors are…
