Hi Andy.
Thank you so much. :woohoo:
This is great !

When you start LinuxCNC all the widgets get restored to their previous value. Thus you have the persistence you wanted.

I will try to install LCNC from master builbot and open your configuration to understand how this solution work.
Is there a limit for the values entry fields ?
I mean in the largest application I need about 250-300 "parameters" values to be available to configure the machine cycle.

regards

Another question.
Can I install LCNC from buildbot aside of the LCNC installation I already have ?

I don't think that there is. There is a limit of 16 analogue inputs to G-code, but this method completely bypasses that interface.
The only possible problem with this is that the G-code can't change the value of any of the persistent parameters, but my impression is that your application does not require that.
(If necessary, the G-code could possibly call user-defined M-code subs to change the values of some parameters, I think)

I don't think so, but there is rarely any disadvantage in running the dev version, and it is a simple config-file change and apt-get command to revert to 2.5.2.

Hi Andy.
Can you explain me a little more about the installation procedure?
So I have a current LCNC 2.5.2 installed on the Ubuntu 8.04 Hardy machine.
I have installed it with the LCNC orginal installation disk started from 2.3.x and upgraded as per forum indication.
In case I make a fresh Ubuntu 10.04 installation (multi boot mode) or 12.04 if possible then can I install LCNC packages
from buildbot ?

You can run master on Hardy, but gladevcp is more troublesome there and I don't think the config I posted will work.

So, I think you need to upgrade to Lucid (10.04) and then install the Master version of LinuxCNC.

I am pretty sure that a "standard" upgrade to 10.04 followed by a buildbot install of LinuxCNC will give you the correct (realtime) kernel in addition to the LinuxCNC executables.

I can't test here (the buildbot site is blocked by my work firewall, and VirtualPC won't run the 10.04 version of LinuxCNC even if I could install it)

I don't know if it is currently easy to upgrade from 9.04 to 10.04 without being pushed to 12.04. I guess following the instructions here will make it clear fairly quickly:
help.ubuntu.com/community/LucidUpgrades

It is probably wise to back-up everything you value, then if it all goes wrong a fresh live-CD install recovery is an option. (perhaps download 8.04 and 10.04 live-CDs first? )

I would like to do this way :

1- Make a disk image for a "just in case" recovery ;
2- Install a fresh Ubuntu 10.04 taken from Ubuntu official site alongside to the actual installation (I've also a Windows Server 2003R2 installed) ;
3- Install the Master version of LinuxCNC from buildbot ;

Can it be a corret workflow ?

I think that should work. If it doesn't then you might need to insert:
wiki.linuxcnc.org/cgi-bin/wiki.pl?Instal...ed_LinuxCNC_packages
between 2 and 3.

If I were you i would leave your current install alone.

Boot from the 10.04 Live CD and create a partition from free space and do a fresh install onto it.

Apart from anything else, if you are currently running 8.04, does your machine support 10.04, if you upgrade you won't find out until it won't start

Hi people.

After some troubles due to the RAID disk controller and Ubuntu 10.04 I finally installed a fresh Ubuntu 10.04.
I followed the instruction from here .
So I'm installing LinuxCNC from Master branch.
From a terminal a made "sudo apt-get update" and "sudo apt-get install linuxcnc".
But at the end I got a message related to the dependencies :

linuxcnc: Dependency : linux-image-2.6.32-122-rtai it is not installable
Dependency : rtai-modules-2.6.32-122-rtai it is not installable
Raccomended : hostmot2-firmware but it is not installable

I'm translating from Italian to English because my Ubuntu installation is Italian . :blush:

Do you have any suggestion ?

Regards
