You should find Plasmac under the sims. It does not get installed for you.

I don’t know where sims is. Sorry I’m not very familiar with any of this.

i have Linuxcnc.list and Linuxcnc.list.save. I also have base.list and base.list.save but im not sure if those pertain to linuxcnc.

When i do this command: $ python /usr/share/doc/linuxcnc/examples/sample-configs/by_machine/plasmac/configurator.py

i get this: bash: $: command not found

Linuxcnc.list

base.list

How do i do uname? if i just type uname in the terminal i get linux
