I got the gantry installed.
The first thing I did was make sure the Y axis rails were as parallel as possible. I made a measuring jig out of an extra piece of Misumi extrusion. I then loosened both end plates on the gantry so the gantry could be twisted to make sure it is exactly 90 degrees to the Y axis rails. I used a large carpenters square to do this. I then tightened the motor end plate to the v-rail. After that was tight and square I did the same to the other end.

I need to install the belt and pulleys next. I think I am going to connect the two sides with threaded 1/4-20 rod. I made a coupler to the motor with a coupling nut I had. I think I got it at the hardware store a while back. I drilled out the threads on one end and left the threads in the other end. I put two set screw spots on the motor end. I hope this will allow me to do fine rotation adjustments to do the final squaring of the gantry. I will use the laser to draw an angle. If the angle is not perfect, I will twist one side forward and re-tighten the lock nut.
