Linux cnc not working

as i said earlier i build linuxcnc-plasmac and it run nice and smooth but today when i try to open it shows an error
i didnt update it or do anything about it

How did you run make, was it 'make' or 'sudo make'?

Cheers, Phill.

tried both with no success with reverse run
but i must admit one thing make install uspace didnt work for me so i just set rip env and ru n it \
DO I NEED USPACE in order for reverse run to function

I think you need USPACE for a non-realtime or a Preempt-RT realtime machine.

Cheers, Phill.

where Are physical pins connections located in plasmac ????

There are none, it is a component.

Cheers, Phill.
