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.
