Permission denied when BlenderCam tries to save NGC

[dacb]

Hi!  I'm trying to generate G-code for cutout of the attached DXF using blender-2.69-OSX_10.6-x86_64_CAM_0.7.0.  I convert the mesh to a curve and calculate the tool path.  When the calculation is complete, I get the error window showing the python traceback (see attached JPG screenshot) giving me a permission denied on the open in write mode for the NGC output file.  I run the app in Terminal from ~/tmp where the DXF that I input is stored.  The app itself is still sitting in ~/Downloads. So the app, the current working directory and the source DXF are all in my home directory with acceptable permissions.  Not sure what path blender is prefixing.  I'm guessing root. When I try to use a full path in the output box it just silently strips the directory separator characters.

Any work around or further checks are warmly welcomed.

Hello, the question is - did you save your file before export?

Blender CAM actually tries to save to the same place where is your .blend file.  - if saving to a location with ok permissions doesn't work, then it's a mystery for me too.

You nailed it.  I wasn't saving the DXF into a native .blend file before doing the CAM generation.  Repeated the workflow but saved out the .blend first and it worked like a charm.

Can't wait to run the G-code. Thanks!
