Syliavski thanks for your reply
I am a little bit confused about what materials is should choose for my gantry. Firstly I was planning to make a steel gantry. 120X60 tubes for the gantry welded together lke this



Then the sides would be 10mm steel laser cutted.


I would even put the green aluminium plate at the front of the gantry, or i would epoxy level the tubes surface so that the rail would be on the same plane.
After that came Dean who adviced me not to have a fully welded gantry so i would be able to adjust. In fact at the above plans i was planning to bolt the sides with the 120X60 beams. Also i was planning to epoxy level tha base plates of the gantry or use shims in order to adjust.
After Deans comments i come up with these plan


with the grey color represent steel and the red color aluminium.
I am really confused about what is better or not. I am starting to make a plan and as i have no experience about the difficulties that i will come up with, i dont know if i am right or if am wrong
So far thanks everybody for your help.
