Which kernel version is best for real time?

Yes that is the correct place to put it.
While testing this, no stress test, no glxgears, no video, no youtube.

next insert lane give error:

[SOLVED] New wifi card causes second parallel port to stop working

Category: General LinuxCNC Questions

lspci -v should list multiple addesses, try all of them.

Sometimes only one address works.

This tool may be useful:

yyao.ca/projects/ParallelPortLinux/

(I made an install script, I think it works)
I don't know the guy who actually wrote this, I just found the program on google. It does work for me.

Never said it wouldn't

Only mentioned on board serial & parallel ports on the ISA bus. Which is still there only not physically.

Backwards?

In what sense?

Java is far, far more feature-rich than Python.

Python does not even have switch statements!


I think the main reason I like Java is the editor (Intellij IDEA CE) is free and good.

PyCharm just is not that great.

And I believe any life without true access modifiers is not a good life.

lspci -v lists my installed Sunix parallel port PCIe card.

I also lists the haxadecimal port thingy (0xe30 or something).

To OP: You can buy a single card with 2 parallel ports from Sunix.

"Asian knockoff", how the fuck would that be read as compatible ?
And where would one find one ?

And once again your stupid senseless post show up and add nothing.

Sometimes you can get less expensive shipping via a forwarder, might take a little longer to arrive, but may work out a little cheaper. But yeah it's been somewhat expensive for shipping Down Under...and no jokes about Qld being 20 years and 1 hour behind....it's non daylight savings time now hahaha

Oh those prices are going to be about 1.6 higher in Aussie beer tokens. So yeah it does end up costing heaps.

If you want to move away from Python, try "Ruby on Rails".
Going from Python to Java is absolutely moving backwards.

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

Why do you need wi-fi?

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).
