I have a computer that runs on Linux Ubuntu. My CNC is 3018Prover.
Can I run the CNC on this computer. I also have a Windows 11 computer which I use to run the CNC.

Check out LinuxCNC
Also Openbuilds CNC has a Debian Linux version of their software.
UGS also has a Linux build.
These are all gcode senders and that’s all you need to run the CNC using Linux.
