Interfaces & linear scale for LinuxCNC

A parallel port has only 5 pins exclusive to input.

There are 8 pins that are bi-directional, but I think they have to all be the same direction (all inputs or all outputs).

It probably depends on the parallel port in question.

If your setup was 2-axis, you could use the 4 output-exclusive pins ans use all 8 bidirectional pins as inputs.

Looks like installing LinuxCNC isn't as easy as installing a casual linux.I remember I had to burn DVD when I first installed it and I borrower a DVD drive to install it properly.I flashed the image using Rufus 4.7 and booted from the USB flash drive - but  then the setup mentions "your installation media coultn't be mounted". Is this a known bug? What's the workaround?Also I was unable to set the BIOS to UEFI mode only. There's no option to disable the compatibility mode - so setup outputs warnings when using USB flash drive in EFI mode.

Works, thanks
