2D CAM for cutting was created by goaran

Hello,

i am serching for a 2D CAM which generates gcode for cuttigng.
I want to input a STL oder something ant then it should generaate the code to cut the part out of a sheet of aluminium with respect to the diameter of the tool.
With pyCam and mygcondegenerator it only can cut 3D objekts out of a block but thats not usefull for cutting things out od a sheet?

Thanks in advance

You might want to check out HeeksCAD and HeeksCNC then. HeeksCNC will derive profiles from the edges of solids. It also works upon simple DXF file profiles too.

Ok, thanks, then i'll try heeksCAD, i tried it a while ago, but it was really buggy, you often couldnt click the dropdown menues and had to go up and down with the mous. Which function in heeksCAM will do this?

you can extract a 'sketch' from the edges of a solid (I've used solids from *.step files) and then use the sketch info along with the profile, pocket, or contour operations to do machining.
I know it takes some getting used to, but once you see how things are done, it makes sense. I've been using it in my shop lately for a lot of gcode programming.

I just tried heeksCAD but there is something wrong with the paths.
is used the installation script form here: code.google.com/p/heekscad/wiki/UbuntuInstallation
when i open heeks then it says could nop open curves.so no such file or dir /usr/bin/Heekscad/HeeksCNC/kurve.so
when i make a link to the file or copy it

sudo ln -s /usr/local/lib/python2.6/dist-packages/kurve.so /usr/local/bin/HeeksCNC/kurve.so

i get the error: undefined Symbol OnStartup

hmm. kurve.so is located here on my Ubuntu8.04 machine:

/usr/local/lib/python2.5/dist-packages/

it used to be in
/usr/local/lib/python2.5/site-packages/

but I guess debian linux based systems are using 'dist-packages' instead of 'site-packages' nowdays.

In any event, when you tried the instructions in the 'Install Kurve' part of that wiki, did you see any commands flying by in the terminal that indicated where it was installing things?

Sorry that it didn't work right away for you.

the link was wrong yes.. , but changing the path didnt help, i get a new error then.

i first made a soft-link as mentioned in the tutorial,
then i changed the link in the pluginsettings - didnt work either,
then i copied the kurve.so (and the two others) to the dir which it was serched for but i allways get the error:

16:58:28: /usr/local/lib/python2.6/dist-packages/actp.so: undefined symbol: OnStartUp
16:58:28: /usr/local/lib/python2.6/dist-packages/area.so: undefined symbol: OnStartUp
16:58:28: /usr/local/lib/python2.6/dist-packages/kurve.so: undefined symbol: OnStartUp

in the console ther is no more information...

so its not a problem of not finding the libs any more.. but i dont know what the problem is now, didnt finde anything in goole either...

Ok, finally got it..

if anybody is intreasted in how:

- use the installation skript
- go to /usr/local/HeeksCAD and rename folder /HeeksCNC to /heekscnc
- set the links to the libs

sudo ln -s /usr/local/lib/python2.6/dist-packages/kurve.so /usr/local/HeeksCAD/heekscnc/kurve.so 
sudo ln -s /usr/local/lib/python2.6/dist-packages/actp.so /usr/local/HeeksCAD/heekscnc/actp.so 
sudo ln -s /usr/local/lib/python2.6/dist-packages/libarea.so /usr/local/HeeksCAD/heekscnc/libarea.so

if you dont rename the folder the postprocessor skripts wont be found.

Have you been able to use it to make g-code yet?
Thanks,
