Config will not open after Buildbot2 upgade from 2.9.4 to 2.10

Category: Plasmac

Yes, there are over 20 messages saying it upgraded but not one message saying it got an error and failed during that upgrade attempt.

That's because it didn't fail, at least not in the eyes of the try/except handler.

You can see I tried several times tying to get to the bottom of it, each generating a message.

The issue is that on two different PC's, the upgrade to a sim install failed without reporting an error which left me in the dark.

I don't know what you mean by "the upgrade to a sim install". Could you please elaborate?

You seem unwilling to actually test such an upgrade process and instead want to blame my installation.

I wouldn't say I am unwilling, even in the absence of steb-by-step directions from you as to how to reproduce what it is you are experiencing, I took my own steps to try to duplicate your issue:

I removed the package version I had installed, added the secret buildbot, and installed master for bookworm. I then launched linuxcnc by typing linuxcnc in the terminal. Navigated to Sample Configurations > sim > qtplasmac > qtplasmac_l_metric, and clicked OK. It worked fine with no update messages. I repeated for a RIP installation, it worked fine with no update messages.

The thing is that this issue has been solved by the aforementioned commits, and a sim config never needs to be updated, as it has the necessary changes. So it leads me to the conclusion that something went wrong in the process of going from 2.9.4 to 2.10.

Are you copying the config and trying to make a usable machine out of it? Or are you trying to actually simulate your machine?

If it's the latter, there's a way to simulate your actual table.

e-stop signal from hybrid servo stepper threw Mesa 7i96s

Category: Driver Boards

As Tommy says connect the alarm output on the drive to to joint.N.amp-fault-in
You may need to invert the signal with the not component. I know I had to.

Script to update 2.9.x ISO to use Linuxcnc Version 2.10 (master branch)

Category: Installing LinuxCNC

This script installs linuxcnc master branch (2.10) after you have installed the ISO on the downloads page.Hakan has tested and refined this further down this thread so I have updated the script here.


You may want to move to version 2.10 to get the latest QtPlasmac for example as the version in 2.9.4 is no longer maintained.
\Instructions:
1. Download  attached script
2. Delete the .txt.extension3. Check permisssions are executible (Right click, Properties and check Permissions tab)
4. Run the script from the folder it is downloaded to: sudo ./update-master.sh

The script deletes and modifies some files in the /etc/apt folder and sub-folders.  It does make a copy of the /etc/apt folder into your home folderI tried on one PC and it worked. On another PC it didn't. If it fails, open the file and run each line individually
after the apt upgrade is complete, running linuxcnc should show version 2.10 on startup in the console and the splash screen.
To update down the track
sudo apt update && sudo apt upgrade
