my 2 cents..
When saving the .dxf, try saving as a R14 format. This is easily read by
most programs. The newer versions are full of headers that may cause
problems. The files are in ASCII so you can examine what's there and
compare versions.
I watched the video. Interesting. It looks like a
Just found a YouTube video about that, problem solved-maybe. Thanks, Todd

Freecad's g-code tools also includes drag-knife dress-ups. I haven't tried to
use them but think I'm about to.
Does Fusion 360 cam do drag knives?
One of these days I might turn this dual boot machine into a tri boot machine
that runs "hackintosh"
Then I can enjoy some of the joys of programs like these without the inherent
insecurity of Windows.

P.S. a four-sided primitive shape was created,
Freecad's g-code tools also includes drag-knife dress-ups. I haven't tried to
use them but think I'm about to. (I have to set up some tool paths for a glass
cutting head we just purchased (which is more or less a drag-knife.)

Reading PyCAM docs these issues sometimes depend of the order the lines
were created and if they form a closed path or if the lines were made from
two verticals then two horizontals then a trim command.I don't know if
dxf3gcode is sensitive to little things like this. None of the software
I really like openscad, and the uphill struggle with Freecad has just begun to
get easier. I had no idea that Freecad could make g code until Todd just told

The beginning of this video has a pretty good illustration of how a drag knife
works (it's different):
I found a couple of DXF files on thingiverse which I downloaded, a couple of
old librecad drawings that I have (pretty simple stuff) and tried all of those
with the same results.
Does PyCAM handle drag knives?

Hi Todd,
The only reason for "messing" with dfx2gcode as a middleman is that it has a
"drag knife" setting, which (I hope means) "on the line, corners over x degrees
exceed by caster amount, lift Z routine for caster change to new direction" I
wanted to see how that routine worked as far as g
All,
I have purchased Q-Cad recently, the DXF portion is free and the CAM costs
extra, and have found the DXF editor pretty good. I have struggled with
the CAM portion that does the DXF to G-code, however. It does not seem
well supported- email inquiries go unanswered. My two-cents.
Best
Freecad can make G-code directly, leaving out the DXF middle man. Have you
tried that?

I've tried two coming from Freecad, both saved as "Autocad dxf", one was a
simple 2D fully constrained 20mm square and the other was the same thing padded
to a thickness of 0.254 mm. I can try a dxf from another source if that is the
problem.

From:
DXF files can be complex and yours might even have problems. Can other
software import the DXF files? Try that, make a trivial change then
re-export to DXF.
The other option is PyCAM. It can generate g-code from DXF also.
Or look at the traceback and see what went wrong. There is something
