I just installed pycam on Ubuntu 8.04 and am starting a test drive. I have tried the examples in the samples folder, and an stl file of my own - without much luck. With everything set up with some care, after the generate toolpath button is pressed - this is the result, regardless of the model.
An unexpected exception occoured: please send the text below to the developers of PyCAM. Thanks a lot!

Any hints on what these messages mean?
psyco is installed and working and the opengl graphics are ok, if a little slow. This is on a Pentium 4 at 3 GHz with 2 GB ram.

Thank you very much for the quick reply. This fix did the trick, and now pycam 0.4 makes tool paths on Ubuntu 8.04.
BTW, I have an EMC-controlled 3 axis wood router, on which I can run the tool paths. The machine was built to carve violins and guitars.

I am having exactly the same problem with Ubuntu 10.04 (running on Amazon EC2) and Pycam 0.5.1.
I have tried to delete the 2 lines, but the problem persists.
Any idea?
Thanks!

Maybe you encountered a similar problem as the one above, but the exact output of PyCAM surely differs slightly. Could you post your details here, please?
cheers,

Hi galfonel,
thanks for your bug report!
I overlooked this problem, since it is exposed with old GTK versions only.
Please remove the lines 2889 and 2890 from src/pycam/Gui/Project.py:
else: log.error("Invalid support grid type: %d" % grid_type)This problem is now fixed in the development repository.
thanks for your report,
Lars
sorry for the confusion - in your version the two lines to be removed look like this:
else: raise ValueError("Invalid support grid type: %d" % grid_type)Lars:

Hi galfenol,
great to hear, that your problem is solved!
Carving violins and guitars sounds very interesting! I would be very happy to see the picture of one of your finished pieces of work …
cheers,

Hi Marcelo,
it feels good to know your name :)
I guess, this thread will solve your problem: http://sourceforge.net/projects/pycam/forums/forum/860184/topic/4822570
