Looking good Scustom :)

Steel plates 20mm thick,except z axis backplate wich will be 25mm.Not sure yet if I will cut all alu at home,or will somebody do It for me.prolly the second option because z axis back and frontplates should be milled.

Are the plates Steel or Ali? Little confused there!

You could avoid the need to mill the Z axis by making each half in three sections, one large plate and two smaller rectangles for the carriages to sit on (they'll bolt through all three anyway). Or, you can do this on just one side. I made mine exactly like you've shown, but only because I knew I had access to a milling machine, and it would have been a lot easier to just go with the three section method. The majority of my aluminium was pre-cut by Aluminium Warehouse, it was just as cheap as cutting it myself and they did a decent job.

Steel frame 60x60 and 180x80(100x80 and 80x80 welded together If i dont find 180x80),epoxy leveled.

Honestly, if I was to do mine again, I'd use Ali profile on both X and Y rather than steel welded then epoxy levelled. The epoxy was just a faff, and probably in the end cost more than the Ali would have done. On my Y axis where I used Ali profile, the whole thing bolted together in a couple of evenings, and both rails went on nicely straight away. On the X, after all the grinding, welding, painting, epoxying, repainting, drilling, etc etc, I'm a little bit fed up of the steel method!! Live and learn...

I'd slightly beef up the T shaped Y axis ballnut connection, making it a triangle or something. Possibly its just that viewpoint, but it also looks offcentre to the groove in the profile which could be fun to mount.

I'd also check that the spindle bit ends up between your X axis carriages when viewed from the side, from the feel of your gantry side plates, it might be just outside of that region. Ideally, it would be halfway between them... but thats a great way to lose travel so I didn't bother :)
