I've noticed several machines framed in aluminum gantry s and frames. Is there a source that has these parts,tubes rails that is good to deal with.
Since I'm reallynew to the cnc world are the cross bars that support the z axis several squre tubes bolted together or one tube or (I don't know how to name it other that a 2"x4"cross bar)
It'd hard to tell from a photo the sizes and structure of the material.
Hope this makes sense, thanks Wyndham
