    Just saw your gantry. what size profile you use?

    I don't like that back plate there, only adds weight and no gain at all against twist nor against bend in the middle.

    Look how i do it on my build right now. Profile 100x100x4 up and down and in between 60x60x3 or 60x60x4 , 2 pieces soldered together, . The Z is 3mm from gantry. Just welded today my 1800mm gantry and confirm that is stiff as it could be. Will measure the bend tomorrow.
