I was looking at the gs2_vfd component source, and though it is mostly
greek (or geek) to me, it looks like it's not tied to Classic Ladder. At
one point it seemed that anything Modbus had to be done with CL and I
just don't need another language to learn. If gs2_vfd can stand on its

Thanks for the help, I have now been able to get emcrsh to work as it is
supposed to. Everything is working as it should, I have also been able
to access emcsh and check out the commands there also. I will now crawl

Hi, for that you need a kernel that's configured to allow 2 cores to be
used.
Our default (most used & tested) kernel only supports one core.
I think there are some testing packages for smp out there, but I am not sure
where.

Are you running latest TRUNK from CVS?
If so, this might be related to the fact that the nml files are now missing.
I think I saw Jeff removing the need for a default NML file, but maybe
emcrsh still needs to get some hardcoded defaults.

you're using feedback speed to decide when to turn off the spindle? why
not use commanded speed instead? or maybe just a timeout based on the 3

can do this)?

John,
It is generally pretty simple. If you are getting connection refused that
usually means emcrsh is not running. Another way to start it from any
configuration is to use halcmd (after starting emc) from a terminal session
as follows:
halcmd loadusr emcrsh
Then see if you can connect with:
