Gene, It is possible to run Linuxcnc on a machine without a X windows environment as I do that on my Chromebook in its Debian based Linux container using RIP. I was going to try on the Pi with one of these images https://raspi.debian.net/tested-images/
This video I watched yesterday explains that the Pi debian images do not include X by default and uses the startsel command to install one Raspberry pi install https://youtu.be/m4UbKD4lWAA I noticed the Debian 11.2 AMD64 installer actually runs startsel during the process. Good luck!
