Sorry, I guess I wasn’t being clear.. I want to account for flex of the gantry rods. I plan to do some complicated 3D joinery on large pieces, so getting the height correct is crucial (I recognize I *might* not be able to do this, but I want to try). I am planning to use a total of 6 supports (2 for the 4′ axis, 4 for the 7′ axis), so I think the flex I most need to consider is the gantry, since there’s no good way to add support to that.
If there’s a way to mitigate this issue with proper assembly I’m all for it.. But it seems like the only way to do that would be to assemble a smaller build, or make some modifications to this one.
