Probably, but I just looked at the error again, and it leads to a question: when linuxcnc isn't running, do you have, in the output of "lsmod" a normal linux parport_pc driver? If you do, its grabbing the parport hardware which is the initiator of the error, and you must prevent that. In your /etc/modprobe.d directory, you will need an emc.conf file, or a linuxcnc.conf file, which contains this: # Remove the '#' before 'install' below to prevent regular Linux programs # from accessing the parallel port. This also means that the linux # parport number may not be used to identify the port in a # loadrt hal_parport. install parport_pc /bin/true And reboot. > > PS.
