Good job Macia! I want the same ... Have you done tests on aluminum?
What are your engines? Nema 17, 23? What is the cnc card? Arduino + shield cnc? If you have pictures, they would have come.
Thank you for your answers ...

Hey, sorry for my late answer.
I haven't built it yet due to some uncertanty about this project. I hope to be able to make some improvements in the design and realize this machine in the near future. Now I'm actually thinking of building a new 3D printer since my Geeetech prusa is driving me crazy.

The motors are 3 Nema 17 (y and z axis) and 1 Nema 23 (x axis)
Arduino+shield would be my goto solution for the electronics since it's really cheap

Nice work! I'd agree with Md4est, that your Y axis seems like a weak point. You have two rails, but because they arn't joined they are not acting like a beam, so will be more likely to sag. The other issue is that this setup might work well for a fdm printer, any force on the x axis will be likely to twist your Y axis. It's a great learning exercise, and very smart part of your process to post it and get input.

Something else to think about is the poured structure idea I've been working on. Faster prints, much stronger parts, and cheap. You can find the pdf I wrote about some of my early work with it here. https://www.thingiverse.com/thing:3468651/files

Looks great, I would add more support to the gantry and use supported rails for the Y axis
