The problem is you have a conscience and are not in this to make a fast buck, only an honest buck.

When the marketing men run the works, then the motto is "Ship it out of the door"
Happened to me when they made a man who used to sell scaffolding poles the Chief Exec of the instrumentation company I worked for.

Yes.  For that reason
I'm not sure I'd consider the Ethernet SS either.
MACH3 has been around long enough that the SS
should really be bug free for
these types of
problems.  I suspect MACH4 will be even worse because if
the
problem is somehow linked to MACH3+SS
then it will never be solved.
Actually
that's not true.  The solution will be "Buy
MACH4.  I'm sure we can
solve it that
way"

What did you
edit in the xml file?  As I say, I can change the
velocity,
exit, try I, go back in, change
it, exit, try it .  and get workable motion.

My Electronic Lead Screw has
had one bug that was a show stopper.  I fixed
it right away.  Since then the people that are
using are happy.  It's an
obligation I
have to at least make the product as bug free as
possible.
Perhaps not enhance it.  But at
least known and obvious bugs need to be
fixed.

The SS has bugs in the tuning setup.
I solved it by editing the xml file
directly.

This will not be
visible, unless you use servos on a metric system.
The problem occurs with large numbers.
My step size is about 0.1 microns or 9600
steps/mm.
It is impossible to set the right
values, through the normal tuning system.
One of several annoying bugs in the SS.
Also something to do with homing, again iirc.
(Been a few years).

Just
like some bugs in M3 threading may not be visible, on an
inch system.
The numbers are so much smaller
in imperial, that they are lost in the
noise.
IIRC..
The problems are with pullouts, angles, and
sometimes feed/rev getting stuck
on.
Iirc this is if you interrupt the threading
(stop, pause or estop), it stays
stuck on
feed/rev.

And also
something to do with waitfor .. waiting for the threading to
start.
Sergey of kslilabs solved it somehow,
with the centipede.

I
junked the SS, and use Cslabs CSMIO, that has none of these
problems,
afaik.
Its
expensive, but very good.
Great value for
money.

OK,
well that is unique to your system, and probably
solvable.

If you are
already tuned, though, it is not a priority, I bet.
