Steel/Aluminium design/build, sorta smallish, cuts ali hopefully

[JAZZCNC]

Oh forgot to spot this but was more looking at the frame than the gantry.! . . . . Mentioned this before many times .!! Wouldn't have the Y axis like that with a rear piece so basicly creating a box with no sides. It's just adding weight and costing money it gives very little strength. Get your self a card box and cut sides out and see what it does.?? . . .Same principle.

It also adds other complications in the build because if the edges are not machined perfectly 90deg it skews the box making it parallelogram which will cause bearings to bind and stick when bolted together.
