Alan, one more thing. LInuxcnc is built and installed in function2 of the uscripts file https://github.com/rodw-au/rpi-img-builder-lcnc/blob/linuxcnc/files/userscripts/uscripts This could receive some love but I don't know bash at all. Note line 50 deletes the /tmp/linuxcnc-dev folder to save space. Commenting that out lets you copy the debs somewhere but as the /tmp folder is overwritten in general use, they get deleted anyway. So save them from the SD card before deployment Perhaps the debs should be copied to another accessible folder before everything is deleted.
