Hi, everyone,
I use Pycam with my milling machine. The process I follow is:
design with OpenSCAD, export as DXF or STL format.
Open with PYCAM and adjust settings for feedrate, speed, bit
size and so forth as required for the project and material. Load the
DXF or STL file and run one of the tool paths.
This has worked for years with no issues. Today, though, Pycam
fails. No errors when the window closes suddenly withour finishing the
job. So I started Pycam from the terminal windows and here are the
error messages:
Psyco is not available (performance will probably suffer slightly)
Enabled 8 parallel local processes
