One last image. this one is from the bottom. i used 1" wide L-brackets to connect the rails to the sides. the rails are NOT very ridgid, they are made of 1x.25" aluminum bar with .5" 1/16wall aluminum C-channel riveted to it. i am going to add a considerable amount of metal to this to make it more ridgid and heavier, so its more stable. i am worried i might have to decelerate the gantry, and i am not sure if thats possible with the software available.
