a busted machine

The Mesa 7i92 uses a Xilinx FPGA. I worked for Altera for many years so it is out of the question.
 

This probably wont change anything but the newer 7i92T are using an  Efinix T20F256 FPGA  (blame it on chips shortage) image missing /media/kunena/emoticons/whistling.png

What is working for me is to backup the whole folder/directory  under /home/username/linuxcnc/configs/   (replace username with the correct name)

Then you can also create a new launcher but to me the easiest way is to copy an existing one then edit it and change the name and the command (4th tab in debian) to something like this: linuxcnc /home/username/linuxcnc/configs/FOLDER_NAME/INI_NAME.ini

Replace above 'username' with your user name.
Replace FOLDER_NAME with the name of the folder/directory
Replace INI_NAME with the name of you ini file

Note: The folder name does NOT need to somehow match the name of the ini file and you don't have to change anything to any file in the folder. You can then have an exact copy of a folder with a different folder name with a different launcher. Easiest way to have a backup on the same machine in case I screw up modifying the in or hal files...

Just a heads up regarding config backup, when saving to USB sticks/memory, zip the folder then copy to drive, otherwise if there are symlinks in use they will not be saved on the USB drive.
This is true for FAT/FAT32/EXTFS formated drives. EXT3/EXT4 formated drives work.

Any ideas on the loadrt [KINS]KINEMATICS issue ? Is the XML file part of the configuration ?
 

Could the XML file be something left over from when I converted from Mach to LinuxCNC ? It was years ago so I have forgotten.

Yes, this could be since Mach3 configs are XML files. Maybe check the date of the file to find out if it was created/edited before you've install linuxcnc?

Also, I have a 'basic' linuxcnc config here with nothing fancy except mesa cards. The only xml file I have is pyvcp-panel.xml. I believe this is for my spindle at speed panel. I also have a backups folder (under the config folder) with several xml files but all with a name beginning with 'pyvcp-panel'.
