You can jam in as many parallel port cards as you have slots. They can be at any free address you have. If the on board one is buggered leaving it enabled will only affect the ISA compatible addresses, IE those hanging off the LPC bus. For the addresses allocated on the PCIe bus different realm, different interface, different bus. Hence the reason on board lpt ports don't show up via lspci, cos they are technically on the ISA bus but physically the LPC bus.

Not a clone, a "compatible" device.

Support comes with a 90USD shipping cost.

Plus due to timezone differences, support will probably be impaired.

Please post the output of lspci -v

Did you try rearranging the cards?

Perhaps order matters.

Some computers are picky about such things.

Most computers I've seen have max 2 PCIe ports, you are fortunate to have 3, though perhaps this broken behavior explains why most PCs only have 2 ports.

Fully agreed — if LinuxCNC ever gets a proper Java API, I’ll gladly throw my Python into the chip tray

Until then, I’ll just keep pretending my Python package has structure and discipline… while knowing deep down it’s all held together by logging statements and good intentions

Oh great you're activly encourage someone to buy illegally cloned hardware, hardware mind that comes from a great company that gives fantastic support.
I've been waiting for you eff up.

Wi-Fi will increase latency for your CNC system.

Your CNC PC should be as minimal as possible.

Ethernet is far better than Wi-Fi anyhow.

Why do you do this, you add nothing, it's of completely no use.
Stop being an oxygen thief and find some other forum to ply your idiocy.
Does this stuff come naturally to you or do you have to work hard to be such a waste of space ?

My apologies to the OP but the user is a menace and I just couldn't put up with his complete uselessness.

Some computers have a terrible BIOS with almost no features at all.

My Dell XPS 17 has like almost no helpful options in the BIOS.

It's incredibly lame.

Most PCs are UEFI nowadays anyways.

If you want to "surf the web", just get a second PC and use that for Wi-Fi.

Your CNC PC should probably be used solely for CNC stuff.

You can also potentially dual-boot (I recommend Ubuntu 22.04 LTS).

In BIOS, see if there is the option to manually assign the IRQ resources and change the offending port IRQ so it is not the same as the WiFi card.
Not all PC's have that option.

Hard to really diagnose without seeing any relevant dmesg output or any info regarding the address of the parallel ports before failure and when failed.

If ptest works Linuxcnc should work.

Python programming is generally something of a band-aid programmed free-for-all.

Java has conventions and structure.

Python is just "whatever floats your goat".

See if you can buy a used MESA board from someone in Austrailia.

Or an Aisian knockoff.

Even in Canada, shipping from China/Thailand is often cheaper than shipping from USA.

(except digi-key)

Yes, the RS-422 is their smart serial connection between the 7i97T FPGA main board and 7i73 and 7i84 daughter boards. Since there is only one RS-422 configured standard on the 7i97T (on TB4), you can only connect one of those two cards, until you reflash the 7i97T to reconfigure some of the pins of the P2 expansion port to provide a second RS-422.

Glad you are enjoying my videos. It is fun to dick around with this stuff

Open source is supposed to allow people to work together; but people don't work together, they insist on doing their own thing.

How does badly recoding chmod help anyone?
