sorry didnt get this out earlier, had to go out of town for work
(yay work :)
but
yes, there is no acceleration limit while edming
( for heidenhain sink eroders, i doubt you'll find as much internal
info from other mfctrs )
some may say that ignoring acc is just wrong
but thats not from
Andy, I agree, they are two separate problems. I just wanted to answer both
questions in one place since they came up here.
My G15/G16 example is very similar to G28 and G30, but the difference would
be that the retract would happen immediately and automatically on abort of
a program (vs at a
Very interesting stuff! I have some ideas for how to implement a more
EDM-appropriate reverse run mechanism based on what you describe. Here's a
short list of new features we would need to address your concerns
1) Retract-to-setpoint-on-abort modal code. If a retract point is set,
the machine

I think that the adaptive feed pin was introduced for wire EDM, and if
it doesn't work properly for that then it ought to change.
so, imo the adaptive feed

would also clear this set point.
Perhaps this pair of G codes could work (chosen
Robert,
thanks for looking into it

i hope your view of the time sale for reversals is
at most millisecs. the immediate velocity has nothing to do with the
previous, there is no velocity smoothing.
I remain confused by this.

interesting when combines with retract
and i see the intermediate point would be easy
( the rufpoint might be an intermediate point from
the cone surface towards the startpoint above the workpiece.
i really have to do some drawings :|
thx for the reminder about G30

Gene,
Yes the cut is in the X axis,
A Z only edm is not worth cnc
it has to cut in any direction, circles in any plane.
This machine is 4 axis XYZC, and huge.
the cut itself was a .02x.375rib cut an inch 'deep',
radially into 72 positions of ID of turbine ring.
These are heat expansion slots.

opens for others, i had it tested by different people, np
no need to join anything, open to anyone given the url.
heres another version you might try

thx tomp
Other than the extra magnification, I had to shrink it to less than 50%
to get it all on my screen, it works perfectly. And there was no

gene,
you're right
dropbox was suggested to me when the msg bounced 1st time
i finally got a tester that never used dropbox
and found he saw same as you
will use imagebin like i always did before
thx for catching this
