Hi Alan,
that is an interesting idea.
from the interpreter perspective there's in principle no issue why some other
language couldnt emit canon calls just alike; possible (with a lot of work)
note that other parts of linuxcnc have some assumptions about the language, for
instance the UI's -
was just a cheap trick
to lower the cost of implementation. There is no reason that we should
keep the labels on control structures. We should then follow the same
rules that C uses.

it looks like you have an existing emc installation and the python code picks
up emc.so from that installation
if it is run-in-place, it shouldnt import emc.so from
/usr/lib/python2.6/dist-packages/
did you run

this a different issue - glade expects the catalog file under /usr/something
and the catalogs arent installed when using RIP

The RepRap dialect seems to be diverging fairly rapidly from what the

like a problem.

There is a standalone interpreter in the LinuxCNC source, though I am

I have some work in progress which enables workpiece Z correction by loading a
mesh of probe points into kins. It was inspired by the recent thread on warped
PCB board milling.
this isnt ready yet, but a starter for the interested:
Sounds like a job for probekins..

I just seem to have skipped, how exactly the surface mesh file is
created by probing the surface in certain points.
that will be a Delaunay triangulation of the probe

than that I'm just an MBA ;-)
Yes, it might be not only cool, but
I found the idea quite intriguing, and thought about integrating the surface
correction idea better. After bouncing a few ideas with Andy, this is what I
have so far:
probekins: a kinematics module which be default behaves like trivkins
it accepts a mesh of triangles which define Z correction

computational geometry isnt my forte but I assume there is a way to approximate
z, within a given error, a probed mesh by a simple parametric function from
x,y; maybe splines or somesuch
