Hi Andy, Ihe link you provided: "LinuxCNC 2.9.2 Raspberry Pi 4 OS based on Debian Bookworm Raspberry Pi 4 Uspace compatible with Mesa Ethernet and SPI interface boards." This is what is downloaded: rpi-4-debian-bookworm-6.1.54-rt15-arm64-ext4-2023-11-17-1731.img.xz
However it installs as 2.9.1 rather than 2.9.2. Paths for that version are also a bit screwed up because now the user folder is 'cnc' rather than 'pi' so now LinuxCNC won't run until the icon is edited to have 'cnc' instead of 'pi' in the path. That or create a user 'pi' with password 'raspberry' as in the old days I guess. There was no problem copying over the /home/pi/ folder into the /home/cnc/ folder but of course the paths were wrong. And Lazarus (Free Pascal) no longer runs but that can always be re-installed. Certainly runs on the LCD screen with wireless Logitech Keyboard and Mouse If the 2.9.1 is adequate for upgrading to 2.9.4 what's the command sequence to do that?
