I ran two CAT5 cables and an extra pull line in conduit out to my shop, works great. Much better in my case than wireless.

I am a network guy and I only use wireless as a last resort.

Hard wired is the way to go

As a retired network guy I'm inclined to agree. I am aware of the robustness of a hard wired connection.

I'm now encountering a very strange phenomena. Having initially installed the 10.04 Live CD on the Gateway Flexatxstc BRO 600 it was working fine. Having now received and hacked the fully height LAN card provided by a friend I decided to download and update the patches to 10.04.3 (which took forever).

Bad move! It broke so I'm now putting the 10.04 Live CD back on, as is, and then try and find what my little BRO doesn't like and what of the patches could/should be omitted

Any thoughts from the panel?

I decided to download and update the patches to 10.04.3 (which took forever).

I presume you mean you ran the update manager.

Don't.

Ubuntu 10.04 with kernel 2.6.32-122-rtai is the basis of the whole EMC install and what it was built against.

If you 'upgrade' the kernel, it will not be a real time kernel, so EMC will no longer work.

If you upgrade individual applications, you will get away with it with some and not others.
If whatever prompted the new kernel number contained changes that directly affect an application,the new version will have been rebuilt against the new kernel and may no longer work.

If you want to upgrade EMC, that is completely different.

You can run whatever version of EMC you like with the current kernel, 2.4.7 is the latest fully supported release, 2.5.xxx is a pretty stable beta used by a lot of people for features which have not migrated to the 2.4 series and which are used by some setups.

And to prevent me making further stupid mistakes again I'm going to be remove the NIC to make it a stand alone machine. G code files can be delivered to the workshop on a pen drive.

It serves me right for trying to be clever.

Still it'll save having to dig that trench for the network cable I mentioned earlier.

Ho hum.

You don't need to do that, its not a mistake you are going to make again!
As John said you can disable selective updates and disable update notifications too, so that you don't get tempted!

Having the workshop computers networked has huge advantages, even for something as simple as being able to do remote backups with rsync.
I write code in the warm of the house, test it in simulation and then 'post' it on my NAS.
I can then download the code from the workshop and 'post' back any modified files so that everything is synchronised.

If you want a hassle free wired connection, look at Homeplugs/Powerline adaptors.

On a good ring main they give full speed broadband (even 200ft away down the garden in my case). If you have a 'noisy' machine, you may have to filter it to use the connection whilst that motor is running, but will save a lot of drilling.

So I get yet another bump along the road to CNC enlightenment.

I shall remember to take far greater care with what upgrade/updates I apply.

I've now reinstalled 10.04 with the 2.6.32-122-rtai kernel to try again.

A cheap parallel card arrived today from HK so now to give it a try in the Gateway. I'll keep you posted on my success or otherwise.
