I just looked at your mentioned Textronix probe Phillip.
U shouldn't use such a probe if you want low interference because it has a very
high RC load in the R component. Maybe U should use a classic 10M Ohm probe
instead and connect that to a 1 MOhm scope?
My impression is that your probe is
Imho , Are U sure U need any particular measurement point device for your pcb
Philipp? At those frequencies U mention U just need a simple pin and a common
ground point at your card to make the measurement. In my days as an RF repair
engineer i hooked my probe at those points with my integrated
Well Mark, I don't think U should enter the Global Warming debate
because the following truth has been thoroughly tested:
1) Too little water kills a man.
2) Too much water kills a man.
I think it's still valid.

Ok, Viesturs!
Well, I haven't been able to closely follow all the issues discussed on this
list but all the posts are saved I guess?
It would be nice to have a closer look at your solutions too.
I now have two older Storebro lathes 260 and 200, with different
control/electronic-troubles but
Well, I have read your arguments and I guess I'm in!
I think I will start with the 2-core Intel atom board Viesturs
mentioned.
And then we have the pheripherals, here is my very preliminary
wish-list, (not much knowledge of my lathe control-interfaces ):

Well, using a battery charger seem to be a high risk approach.
What Pico seem to delveir is I guess the right thing, a regulated and
shortcirciut-proof device intended for computer boards?
Potential problems with battery chargers as powersupplies are:
- Probably unfiltered DC

Hello all and thanks again for your support!
Have been busy at the shop trying to write some code for the 260 and doing
other tasks.

Noticed the lists persistent discussion of the LinucCNC trajectory planning
functionality.
As a system designer I'm curious about the mentioned rule ability to stop at
end of next block and wonder what the rationale for such a rule consist of.
As a programmer I would also find it convenient to

no Virtual boxes in a real system but you can do a lot of preparatory
work in the box I believe...

Well, Peter, after 12 hours close encounter : It might be a version
of the machine without cover, this CNC is built on a tradtional lathe
setup, just adding servos and a better spindle engline, some sensors
and this Sinumerik/FANUC 6 control and that's it !
On the other hand, your machine

According to Daves FANUC link: http://www.cnc1.com/News/customer-

it tells us that Fanuc 7 was the version developed in cooperation
with Siemens and it was marketed in two separate hardware versions,
one from each company.

I got a task from my coming boss and that is to configure an old
Storebro 160 Lathe running Sinumerik 6T.
There is an issue about resetting the coordinate system to the
workpiece and doing tool compensation setup.
He also told me the Siemens system should be the same as a FANUC 6 ?
Anyway,
There might of course be a possibility that the machine is upgraded...
About the connection to Siemens the boss told me they did cooperate
briefly in the eighties...
About the encoders I will look att that, going there on Wednesday.

It seems I have to give LinuxCNC a closer look.
There is a low cost commercial alternative in MACH 3.

I know it's based on Windows with some kind of realtime extension who
