Hey Kirk
Just cause I'm curious, Why didn't you use classicladder to select tools from
your turret? It has timers good to 100ms min. Then you could use the tool pins
from emcmot to control the turret -automating tool changes to use regular T and
M codes,instead of using M101- or you could use

Gentlemen,
We cheat. The edm uses through the spindle/tool flushing and
dielectric oil. The electrode is a copper tube. The tube is not
completely hollow. The tube has a web in the center of it. This allows
it to remove the whole plug instead of leaving a core.
You will have the same flushi

Hi Ken
I've not tried this with your modified interpreter but with the old one,
you could save a variable from run to run if you manually add it's
numeric name and value to the .var file. That done, it will take
whatever value it's holds at the end of a run.

[TRAJ]AXES should probably be set to 8. Here's the explanation from the
documentation:
One more than the number of the highest joint number in the system.
For an XYZ machine, the joints are numbered 0, 1 and 2; in this case
AXES should be 3. For an XYUV machine using ``trivial kinemati

What you're talking about here, I can do with a combination of manual

is just as easy to manually operate a cnc as it is to operate a

You'd want to issue a command, like 'face end'. The control program then
sends generated G-code and receives feedback to/from the lathe to find and
measure the workpiece. It then selects a tool, speed, and faces it off until

Actually emc2 does have that, as a somehow hidden feature.
If you put a parameter in your .var file, the interpreter will save the last

I didn't fully understand the intent. You're aiming for tools to do relatively

Do you mean something like:

The idea of this is that a GUI would let you generate calls to predefined
gcode subroutines.

I am not for a second suggesting Interactive machining should replace
conventional CAD-CAM, Gcode generation. As Stuart describes there are
large complex machines for which Gcode is the appropriate tool, and EMC
works very well.
However, I see application for the much simpler Interactive work.
