Everything ordered including the steel for the structure. Still have not ordered the laser cut parts. Untill i have the rails and ball screws at hand.

And here comes the first major problem. The place where i found the 140x80 profile for the gantry refuses to sell me 1m even they have promised me before. . Now i have to buy 6m , or change the design.

At the other place where i would buy the rest of the steel, i found some pieces of 100x100x4 box profile. And generally they will sell me everything cheaper and help me in their machine shop. So now i am contemplating soldering 2 pieces of 100x100 and making the gantry 100x200mm. That would change the design of the gantry widening 2cm, one at each side and making it higher by 6 cm.

What is your opinion about this change? The ball screws will be further 2 cm from the z plate. And the upper bearing slides and rail will go 6 cm higher.
