Newbie looking for a hardware configuration based on Raspberry Pi

Hello everyone,
I’m not sure if I posted this in the right section, but if I did, I’ll move it to the correct place if possible.
My name is Marco, and I recently came across LinuxCNC. I’m planning to build a new 3-axis CNC (which will be upgradable to 4 axes in the future) using LinuxCNC on a Raspberry Pi 4 or 5. I’ve found there are a lot of options available and would really appreciate some help deciding which one to pick.To clarify things a bit, here are some of my findings:These are some options I’ve looked at:
1) Linumeric V3
2) 
3) github.com/ChrisWag91/PI-LCNC
4) www.forum.linuxcnc.org/18-computer/51816...lug-and-play?start=0
5) github.com/jzolee/HAL2UDPI’ve tried to choose one, but I’m still quite confused, so I thought I’d ask someone with more experience than me.
Since I’m Italian and don’t speak English very often, there’s a chance I might have made some mistakes in this post.
Thanks a lot in advance for your patience and attention!

PS. in the past, i had the opportunity to work with a 3-axis cnc running on mach3 via the LPT port. If it matters by any chance.

Ciao.

Meanwhile, congratulations on the good work.

I am also Italian and have been working with LinuxCnc and Raspberyy for a long time and I took care of its translation into Italian.

If you want I can give you other directions

Salve,
Thank you so much for this new resource. I think i'll start playing around with it as soon as i get a Raspberry Pi. i wonder what is the maximum control frequency using this solution.
I see you are a professor. I'm currently a computer engineering student at UniCal. i wish there would be a similar project at my university .
Hope you do well. Thanks again.

I have been retired for a couple of years now.
If you want, I can give you the name of a UniCal teacher who, in addition to knowing me personally, could answer your questions.
In the meantime, I'll see if I can find the digital copy of this thesis which could be a good starting point for your work.
 

Hello, it's been a while... i hope you had a merry Christmas. It sounds awesome to me. But i think it will take a while because i am preparing my last exams. Maybe there's a chance i may already know the UniCal professor you're talking about, if he's in my department (DIMES).

Hope to hear you soon. Sorry for the day in my reply, but I'm studying and working too.
Thank you so much

The professors who know me and I think deal with these issues are at DIMEG.

You can go to them saying I was the one who reported them and ask

infodimeg.unical.it/associate_professor/card/152

infodimeg.unical.it/associate_professor/card/148

Thanks again, professor. have you had the opportunity to look for the digital copy of the thesis?
If I'll need some help I'll reach out to them. If we wont hear any time soon i wish you a happy new year.

Something has changed on linuxcnc between then and now, but not much.
In particular, the function for using GPIOs which was previously hal_pi_gpio and is now hal_gpio

The image of RaspiOS with Linuxcnc is available in this link
