I've read a posting on another forum where the author states he's running LinuxCNC with a Raspberry Pi using the Pi4 (and now Pi5) I/O pins configured to duplicate the PC parallel port. With the quad core processor on the Pi is it now fast enough to duplicate a PC with a parallel port or is the guy full of BS? John
