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.

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.

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.

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.

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

Hi all,

I’ve developed a custom Python package — and not just a loose .py file, but a real multi-module package, complete with pyproject.toml, unit tests, internal structure, and even a __str__ for logging prettiness. Yes, I know, it’s total overkill for something that just drives the lubrication pump… but hey, it’s fun

The code I wrote can be found here if anyone is interested: github.com/johanvergeer/maho-mh400e-conf...ree/main/lubrication

Now I want to use this package from a Python script that’s launched via loadusr in my machine config.

Some context:

• The script uses linuxcnc, hal, and qtvcp modules.
• LinuxCNC runs on the global system Python interpreter as far as I can see, which means my package has to be available outside of any virtual environment.
• Installing with pip install . into the global Python environment technically works, but it’s strongly discouraged on modern Debian-based systems due to PEP 668. I’ve already seen Poetry try to uninstall half of /usr/lib/python3 
  
• Virtualenvs don’t help much either, since they can’t see LinuxCNC’s compiled modules.
• Adding my repo folder to sys.path is possible, but feels like duct tape.

So… what’s the best practice here?

• Is it acceptable to install your own packages into something like /usr/lib/python3/dist-packages/?
• Is there an officially recommended way to include custom Python packages that need to be imported across multiple files or used in different HAL components?

Or am I simply in “here be dragons” territory and should stick to a bunch of flat .py files with global state? 

Any advice or patterns you use would be greatly appreciated!

Cheers,
Johan
 

Yep, that's definitely the problem.  QtPlasmaC does not intend for G92 to be used.  In fact for the Master branch, we disabled it entirely:

Master Docs

I would recommend you use the peripheral offsets process to set up your laser pointer:

Peripheral Offsets

Then you can use the process described in the LASER section to set your origin.  The bonus is that you can use this to rotate the work coordinate system to account for a sheet of material that is not quite straight.

Hopefully that helps get you straightened out.  Please let me know if you have any questions. 

If its still of interest, the limit switches are normally closed, and go over a relay to the controls.

Setup:
LinuxCNC 2.9.0 using Axis, configured with Stepconf
Dell Precision Workstation T3500, 8g ram
Radeon HD 5700
Two identical Sunix PCIe parallel port cards
Mint Debian Edition 6
#1 SMP PREEMPT_RT Debian 6.1.128-1 (2025-02-07)
6.1.0-31-rt-amd64
Why do I have two parallel port cards? Some time ago, I damaged the MB parallel port.
This setup works great.

When I add a wifi card (TP-Link PCIe Wifi card AC600), the second parallel port card address changes (per dmesg). I updated the hal with Stepconf for the new address. Now in Axis, the Machine Power button is grayed out, like the estop circuit is open. Estop-in is on the second parallel port card, so I'm interpreting this as the wifi card is somehow blocking the second parallel port card.
I shutdown, removed the wifi card, updated the second parallel port card address, and it all works fine again.

Put the wifi card back in and ran ptest
forum.linuxcnc.org/18-computer/4743-parallel-port-tester   (thanks BigJohnT)
Both parallel port cards work with ptest, with the wifi card installed.

Advice will be greatly appreciated.

I was considering getting these drivers. Did you manage to get them to work, or should they be avoided?

sorry Snow.

1. no tried again with a different file.
2. yes, cut, then frame. its a time lapse.

I did some testing tonight and all is good until i zero off the laser pointer.
The code i'm using for this is
G92 x0 y0/ G0 x-2 y 104/G92 x0 y0

Is this code wrong?

Also, everything is fine, until I zero on the laser pointer. 

Hi all 
I need to order a 7i73 and shipping is $90 USD to get it to Qld Australia. This may be the unavoidable cost but I can't justify it for a $49usd board.
I'm happy to wait a couple of months if necessary and combine freight with others ordering from Mesa.
If your considering ordering and would like to combine our orders and split freight costs PM me. 
Cheers Brad.
