Hi all,
I need to set a couple outputs based on which tool is selected. I only have
3 tools. I expect others have run into this issue. So far the easiest way I
see is to convert iocontrol.0.tool-number into a float and then use
comparators on that value to set the states of my outputs.

Jacob,
If you just want to issue commands via a command line interface you can use
linuxcncrsh. It is basically a telnet like interface. You could also shell
in via ssh and then connect to local host to both go over a standard port
and retain encryption.
Bruce,
Here is a link to light sequencing and DMX decoding using an Arduino:

I personally do not know much about theater lighting but thought this might
be of interest. If you are located in the US, the Arduino
Walter,
I have not been following this thread, so I may be talking out of school,
but don't you just need to have linuxcncrsh run on the BBB running linuxcnc?
That simply requires 'loadusr linuxcnc in the hal file or
DISPLAY=linuxcncrsh in the ini file. It then starts with linuxcnc and does

Well just get a generator working off a Hot-Cat

in favor of Hub Motors
Off chance, does anyone know of a North American if not US distributor of
Axor motors and Microspeed drives? I thought I had come across one in Canada
(Vancouver IIRC), but I do not seem to be able to find them ATM.

Lars,
If you have another user interface running, the first interface to see the
error is going to swallow it. Since a local interface generally updates faster
that one over a network, the odds are that the local interface will see it
first.
This is a known limitation of that interface.

Wesley,
For those basic functions, could you just use linuxcncrsh (emcrsh prior to
version 2.5), see:

The protocol itself was never intended to be secure, but you can tunnel over
SSH to achieve that.

Thanks Eric.
I actually just started looking into that as an option. In general, telnet
is frowned upon for security reasons. But I have other systems that use it
and we
Hi all,
The hard drive failed on one of my customer's machines. They were running
emc2 2.4.7. I was trying to reinstall that so that I can run the known
working configuration without modification. I was trying to run this script
file:

Referenced here:
Re-running the script does not repeat the stuff that succeeded, only that
which failed. Here is what failed:
The following packages have unmet dependencies:

Replying to my own post, this looks like the problem, and possibly the

Ok, I added:

to my sources.list file and then was able to install:
python2.4-minimal
python2.4
python2.4-dev
But when I run the install script I am still getting the same error.

Thanks, I decided it was going to be easier to just upgrade to 2.5.

I think I found the problem. The wiki page you looked at is out of date -
it says at the top in bold to go look at this other page instead:
