parallel port no longer detected by LinuxCNC and neither by dmesg, failed? was created by gzcwnk
It was working but I tried a new BOB as the one I had was failing and well I am wondering if the new BOB damaged the PP card?

:(

What voltage does the BOB use ?
Is it a PCI add on or built in parallel?

The Bob has a seperate 24v dc supply. PCI add on card

dmesg (dmesg | grep para) doesnt show a paraport

Insert the card into another PCI slot if available, if not, clean the contacts on the card and motherboard.
And 24V will mess it up if any miss wiring occurred.

How could I mis-wire it? its optically isolated?

OK, is it possible the address has moved and linuxCNC cant see it any more?

Yes it is, and to prevent that from happening you have to set the BIOS to manually assign addresses and IRQ.

Did you just post another topic and then delete it ?
It was there, now it is not, something about a Dell 9020 ? :(
