Test rig changes.

I was considering making a set of tall OX gantry plates to increase the working Z height distance of the LaserWeb test rig (an OX derivative), but I had an epiphany in the middle of the night. So early this morning (about 4 a.m.) I started on some changes. I have modified how I have attached the 2080 V-slot Y rails to my torsion box table. Originally, I had only 3/4" of the V slot extending above the table with 2 horizontal rows of screws attaching the v-slot to the table from the outside. Now , I have raised it another 3/4", using one horizontal row of screws on the outside to hold it to the table, and on the inside of the v-slot on top of the table I have placed 3D printed angle corners to connect the v-slot to the table. This has served 2 functions. Firstly, I gained an extra 3/4" of working Z height, and secondly, the v-slot is more accurately parallel to the table surface and kept at a perfect 90 degrees to the table. The 3D printed angle blocks (stl downloaded from the OpenBuilds site) are plenty strong printed at 100% infill, I use a t-nut in the v-slot to connect the block to the rail, and deep groove drywall screws to hold the block to the table. I will also be changing the spoiler board from 3/4" MDF to 1/4" MDF, gaining another 1/2" of Z height working space. SO all together, I have gained 1 1/4" of extra height, without having to remake the gantry plates.
