Just added EMC2 to my computer and....

[austin.mn]

I have a computer in the shop driving my laser with EMC2 and Ubuntu 8.04

I keep seeing all the cool things that can be done with EMC and wanted to learn more in a comfortable environment and I loaded it onto my Laptop with Ubuntu 10.04 Now I have lost my wireless connection. I am pretty much a nuub to EMC and Ubuntu. I am able to go online with a wired connection, but haven't come up with a solution to getting my wireless back.

Any Guru's out there that know what I need to do? The laptop is a Gateway MT6451 with a Broadcom bcm4311 wireless setup.

You should be able to install the NDIS wrapper which will allow you to load the windows wireless driver.

Installing the NDIS and the wireless should only take about 5 minutes (maybe after another half hour on google to see the steps).

I tried that last night, got frustrated and quit... I will give it a shot again tonight.

I am still learning and linux is a bit different than windows. quite a bit...

3am and I am still not getting anywhere....

I got the ndiswrapper to work. I spent a lot of time trying to do it through terminal, but I am just too ignorant about ubuntu to be able to make that work. I was just about to hit the sheets and I thought maybe there was a tutorial on youtube. Sure enough there was. Within minutes I had ndiswrapper up and running. I thought it would only be a moment and I would have wireless internet.

Downloaded two different windows drivers, bcmwl5.inf and bcmwl6.inf

First I tried bcmwl6 and it says 'unable to see if hardware is present'
Then I clicked OK and under that driver it says 'hardware present: Yes'
But it still didn't work.
Then I tried the bcmwl5 and it says incorrect driver

Is there anyway I can dual boot the computer so that I can run with the old kernel? I lost wireless after the reboot and it switched to the realtime kernel, so I assume that is where the problem came from. My computer attached to the laser has an option screen on bootup to select the ubuntu version or windows.

Yeah, got it working! WOOO WHOOO

There is a startup manager that you can load in the get new applications thing. I was able to change the default kernel. I haven't tried to run emc yet. I would think it is still going to work, at least for what I had intended, which is to just explore all the cool stuff. It won't be hooked up to a machine, just plan on trying to learn a bit more about what it has available.

So, yippee skippee, I can watch more youtube tutorials and not be tied down anymore.

It is BAD JUJU to run EMC2 on UBUNTU10.04

In order to run EMC2 on UBUNTU10.04 you need to recompile the kernel with RTIA library.

Better option is to download the ISO image of 8.04 and burn it to a CD.

Use this CD to then install Ubuntu and EMC2.

The image can be found on linuxcnc website.

There are pre-compiled packages (and kernel) ready for 10.04.

Its still considered BETA IIRC because there have been issues reported for some quad core systems.

Single and dual cores appear un-affected.

Party on!

I seem to be preaching to converted... mea culpa.

The main reason for me putting it on my laptop is so I can gain a little more experience with it in a comfortable chair. I want to be able to learn how to do a lot of things that I just haven't messed with on my machines that I use for work, don't want to go screwing them up and loosing a few days of work just trying to fix them. I don't see that running it on a non-realtime kernel is going to be a problem for that. If it is, I can always boot it into the correct kernel for those instances that I want to spend some time screwing around with it.

I run EMC on my Ubuntu 10.04 laptop (and a couple of desktops) in SIMULATION MODE. It works great.

Install it with this shell script:

GET http://www.linuxcnc.org/lucid/emc2-install-sim.sh | bash

I use 8.04 for actual machining.
