Sir,
Please tell how to change pin status ( input , output, active low and active high) in gpioinfo.

Many thanks.

Does LinuxCNC have a steep learning curve or am I overthinking too much?

I my case it was/is a steep learning curve. Why? I didn't choose the easy way. You can use the parallel port, but if you have the money, just buy a mesa-card that is supported by PnCconf, a configuration wizard. 7i96s for example. And use a decent intel/amd pc, not a raspberry pi like I did.
And, read the Linuxcnc manual. There is a point where you probably don't understand is anymore, but just keep reading. And after that, read it again. Use the search function on this form if you really get stuck.

I don't know about other diy machines, but if you look at the wiki of PrintNC, you can find a lot of information to get started.

Please tells us more about your experience with metal/aluminium/wood/linux/electronics/plc's/computers/etc... 

I understand the discussion/frustration about linuxcnc, but that should be in another topic I think. 

This problem was already known:
forum.linuxcnc.org/9-installing-linuxcnc...-pi-5?start=0#285243
My advice is to use this new module (hal_gpio) which, in addition to working on Pi 5, in my opinion is more versatile and easier to configure

For changes to be made to .hal files it may be useful to refer to this video

I'll have a read of that link once I get squared away with some coffee here. I came across another thread in the general section yesterday where a fellow made a slight modification to an older iso image (2.8.0) and got it to work on a Pi3B. It involved modifying the config-rt.txt file in the \boot section on the sd card post-etcher and pre-Pi3B boot. Figuring I needed a Linux machine to made this edit, I went off and installed a virtual box, along with xubuntu (which seemed to take forever). I then began to dig for how to "see" the sdcard in Linux, but before I did that I discovered that the \boot section on the sdcard is accessible by windows and I could easily see and mod the config-rt.txt file with someting like notepad++. That's as far as I got.

Here's the thread where I came across this approach -
forum.linuxcnc.org/38-general-linuxcnc-q...aspberry-pi-3#228816

The error is
HAL_PI_GPIO: can't open /dev/gpiomem: 2 - No such file or directory

/dev/gpiomem doesn't exist

A replied previously
At the moment (2023-07-16) this driver only seems to work on Raspbian as the generic Debian image does not set up the correct interfaces in /dev/gpiomem and restricts access to the /sys/mem interface.

So have will have to start with a Raspbian image, build & install a rt kernel and then build & install linuxcnc.

But just for completeness can you run
and report the result

please help

you probably need to install pip first
sudo apt-get install pip
something like that probably

Thanks for reply, sirI am already add user rohit to group gpio but same error show.

I certainly can't. I got alotta help from the Machinekit group. That was years ago, and I have no idea what state it is in now, Machinekit is pretty much dead. Maybe you'll find some help in my old thread:
groups.google.com/g/machinekit/c/eVhvTnuhblE/m/uv1Ml-gGAgAJ

Gotta watch out as MK is a bit different than LinuxCNC. It's a fork of LinuxCNC but they split the "CNC" stack off into a separate application. So the DE10 was meant to run the Mesa side in FPGA fabric and the realtime Linux/HAL stuff was meant to run on the DE10's ARM cores. The rest of LinuxCNC was supposed to run on a non-realtime remote computer. You can actually run everything on the DE10, which is what I did. It's like running LinuxCNC on a Raspberry Pi 3 with a built in Mesa card.

I haven't touched it for years cuz MK is dead. Be nice if you could get the Mesa side working with LinuxCNC, I could knock the dust off these...

 

The DE10 Has a ton of IO

Thanks for the feedback and suggestions ! I have been able to bring the Rpi3B back to life with the proper selection on the Raspberry OS software. They seem to have versions that go way back.

I guess the next step is to head over to the link you provided and start to dig to see if I can find any info / images there re: LinuxCNC installation.

As to the deletion of the outdated info on the Remora docs site, I think that perhaps a notice that the information is now out of date but the general steps remain the same (if they do remain the same). As a noob I did find these steps to be educational even if they did not get me the exact process to get Linuxcnc on the Pi3B.

Thanks again and I'll continue on with my searching and learning.
Cheers,
Lewis

trywhere username should be PI or whatever user name you are using.

 Thanks for reply sir i am attached error please see

Don't use screen shots taken at a bad angle impossible to read. Copy and paste the text only.

Thanks for reply sir please tell now what is solution of this problem

As per:
