INSTALL.TXT
View file @ dd10fa15
Currently it is not necessary to install the software,
simply unpack the distribution archive, and run "python pycam.py"
from the archive directory
DEPENDENCIES:
-------------
Windows:
--------
Python 2.5
PyOpenGL : http://pyopengl.sourceforge.net/
http://downloads.sourceforge.net/pyopengl/PyOpenGL-3.0.0.win32.exe
TOGL: http://downloads.sourceforge.net/togl/Togl2.0-8.4-Windows.zip
(just copy the directory Togl2.0 into Python25/tcl)
GLUT : http://www.cip.physik.uni-muenchen.de/~georg.hennig/downloads/glut-3.7.6-wheel_mingw.zip
Unix:
-----
Install PyOpenGL, Togl, Glut using your package manager.
Or compile from source:
http://downloads.sourceforge.net/pyopengl/PyOpenGL-3.0.0.tar.gz
In case Togl is not available or not working, I suggest to compile Togl yourself.
http://downloads.sourceforge.net/togl/Togl2.0-src.tar.gz
Install the source packages for tcl and tk using your package manager.
cd ~/Togl2.0
./configure --prefix=/usr --exec-prefix=/usr --enable-threads
make
make install
or, failing that, for download the sources for the same version of tcl and tk
as you have installed on your system:
(http://sourceforge.net/project/showfiles.php?group_id=10894&package_id=10452)
Togl only needs access to a few header files that are not part of the
binary distributions...
I unpacked the tcl and tk sources next to the Togl sources in my home directory, then
cd ~/tcl-8.5.5/unix;
./configure
cd ~/tk-8.5.5/unix;
./configure
cd ~/Togl2.0;
./configure --with-tcl=$HOME/tcl-8.5.5 --with-tk=$HOME/tk-8.5.5 \
--prefix=/usr --exec-prefix=/usr --enable-threads
make
make install

INSTALL:
PyOpenGL : http://pyopengl.sourceforge.net/
http://downloads.sourceforge.net/pyopengl/PyOpenGL-3.0.0b5.tar.gz
(requires TOGL)

http://downloads.sourceforge.net/togl/Togl2.0-src.tar.gz
(download tcl-8.4-src.tgz and tk-8.4-src.tgz and compile and install togl)
(on windows, this also requires GLUT)

RUNNING:
extract the archive and run "python pycam.py"

as a practical approach, you would probably:
1) use the Cylindrical cutter with the PushCutter Pathgenerator and the Polygon PostProcessor to do the "rough" cutting
1) for "rough" cutting,
use the Cylindrical cutter
with the PushCutter Pathgenerator
and the Polygon PostProcessor in "x" or "y" mode
2) use the Toroidal cutter with the ContourCutter Pathgenerator to do the "semifinish" cutting.
(it's not yet implemented, so you can skip this one for now :-)
