Maybe neither.
Stepconf creates parallel port stepper configs, pncconf creates Mesa-card configurations.
Neither of them automatically create a remapped toolchange configuration.

Unless I am mistaken, you had a working configuration previously? The first thing to do is check that that still works.
Then start the sim/remap/rack_toolchange config, and see if that looks like it works (it won't move a machine, it's a simulator). Make sure that you select the option to make a copy of that config in your home/linuxcnc/configs directory.

Now make a copy of your existing, working config by copying the directory and changing the name.

Then copy the extra files from the toolchange example into your config.

Then look through the INI and HAL files of the sample config, and copy anything "toolchange-ey" or GladeVCP-ish or Pythonesque into your INI and HAL files.

You will need to edit the toolchange ngc files to make the correct moves for your rack location and spacing.

Renamed the EMC2 folder to linuxcnc but my old configuration will not launch nothing happens at all

Tried using the wizard to make a new test configuration all went as usual but when I launch the test
I see a 2.5 splash then axis appears for a second then it crashes and I get the errors box.

Is the existing config available as an option in the configuration selector?
I think that the problem with that configuration might be that the INI file refers to HAL files in the emc2 directory, which has been renamed.
This is causing a lot of problems, but big expensive scary lawyers left us with no options.
Have a look through the original INI file looking for file paths with emc2 in them, and try changing them.

So it looks like you are on 2.5, not "master" which comes up as a 2.6 version,

[/quote]custom_postgui.hal:20: signal 'spindle-at-speed' not found[/quote]This is why the configuration is not loading, there is a custom_postgui HAL file in the config which refers to a signal which has not been created in the main HAL file.

I think getting your old config working is likely to be the best solution.

Perhaps I should start over reinstall 2.4 from the live disk then upgrade from there
then use the 2.6 wizard to create a basic configuration then cut and paste the
customized parts of my old configuration file back into it.

I don't see any reason to go back to 2.4. A brand-new LiveCD install of 2.5 might make some sense though. (backup all your existing configs though).

Then a buildbot update to 2.6 (deb buildbot.linuxcnc.org/ lucid master-rt deb-src buildbot.linuxcnc.org/ lucid master-rt )
Which version of Ubuntu are you running? You need the correct deb entry from the buildbot. You can run "master" on Hardy or Lucid, but need to choose the correct package.

Yes this how I would like to proceed but there are two problems #1 in the past Linux 10 had terrible
latency performance on the Dell computers I have while Linux 8 work fine. #2 just to see if anything
had changed I downloaded a new Linux 10 with 2.5 and made the live CD checked the CRC OK
but the install process hangs and nothing happens.

So for the moment I will proceed with a second attempt at the long form upgrade process.

OK I think I have finally succeeded in upgrading to 2.6 I used the wizard to create a test configuration which works
when I launch it. Now I need to ether modify my old 2.3 configuration or just cut and paste the custom parts of
my old config into a new one created by the 2.6 wizard. Not sure which is the easiest method. Then I can tackle
remapping the M6 G code .

OK I have picked through the remapping doc and had a go at making it work
but no luck on the first try. I think there is some missing components.

The doc refers to a directory that I can not locate configs/sim/remap/python-stdglue/remap.py
and I get the error list which for some reason I can not copy and paste??

So I have to transcribe a line from the Debug file
Python plug in required for prolog=, but not available: 35 REMAP = M6 modalgroup=6 prolog=change_prolog ngc=change epilog=change_epilog

Also where do I place the file change.ncg ?

Thanks

I think that the problem is that the LinuxCNC startup script insists on copying the files to your home folder, but doesn't bring them all.

If you open a terminal and type
linuxcnc /usr/share/doc/linuxcnc/examples/sample-configs/sim/remap/rack-toolchange/racktoolchange.ini
then you should get it to launch properly. You can then go to the MDI window and type M6T3 and watch it do a tool change.
So, it works. However you need to find all the files, they seem to be in a combination of usr/share/doc/linuxcnc/examples/sample-configs/sim/remap (support files) and /usr/share/linuxcnc/ncfiles/remap-subroutines for the ngc files.

Looking in racktoolchange.hal, it calls three HAL files, only one of which you need to duplicate / include in your HAL.
The [PYTHON] PATH_PREPEND and PATH_APPEND in the INI file will need to be modified to point to your actual routines.

I think it is mainly a case of moving all these files into your own config directory, and making all the references to them in the INI file point to the right places.

Sorry, I thought it was a lot tidier than this.

hi, I was away for a while.

I suggest to cd to /usr/share/doc/linuxcnc/examples/sample-configs/sim/remap/rack-toolchange and then run 'linuxcnc rack-toolchange.ini' to see whether this makes any difference.

I need to look into the 'selector' integration
