You are using a simulated-realtime version of LinuxCNC, so testing

New user here and new to CNC just installed LinuxCNC on Ubuntu 22.10 and after connecting up USB to a chinese board to just confirm software to board handshake works, I get the error "You are using a simulated-realtime version of LinuxCNC, so testing / tuning hardware is unavailable."

[ ] create simulated hardware configuration  box IS UNCHECKED.

Thanks for any pointers!

 

1) LinuxCNC does not work over USB (it needs a low latency communication channel)
2) Probably a moot point because of 1), but: you need to install (and run) a real time kernel. Did you do that? What does 'uname -a' say?

Thank you for sharing that information.

My cheap amazon CNC came with an offline controller (linked below). The controller connects to the mainboard. Do you happen to know if I could swap out the offline controller and use that port on the mainboard to connect to connect to a LinuxPC (running real time kernel) serial port?
