This is my first BUILD please help.

[DigiSoft]

Going off advice given to my design, and the veiws i know others share I'd say it seems to have the right things in the right places pretty much.

Critisism: flip the stepper motor and mount it on the back then use a belt and pulley system. This will reduce resonance, as well as other things? (correct me)
Perhaps also mount the ball nut inline with the rails, might help give greater travel in x?

Finally, ignorance is getting the better of me, are you really from chernobyl?

Hahahahahahhaa no my friend, I am not from there. I just put it like that :D
Thank you for the help.

Can you tell me if the Y distance of the rails (vertical distance between the Y rails) is better to be 150mm or 200mm. Y will be 1140mm long

PS: I am still working on the Y boll-nut. I just put it like that, it is not in place.
PSS: I was also thinking about belt and pulley for the Z but I don't have those parts and it will complicate my design. What do you think? Is there that much difference?
All aluminum parts are 20mm tick.

I changed the design little so the Y distance between the two axis is 150mm


Do you think this is better?
