X Gantry Plate
The X carriage holes the two Z rails used to support the Z carriage.
The heart of the X carriage is the X carriage plate shown here.
It attaches directly to the two extended trucks mounted on the X rails.
The carriage plate is 7" x 12" and is cut from 1/2" stock. In my case I use 1/2" Corian.
X Carriage Assembly
On the front of the X carriage plate the two 20mm x 300mm rails are mounted and held in place with #10 x 1" machine screws.
On the back is a Dumpster CNC ACME nut, mounted on a small angle bracket.
The X carriage plate mounts to the two carriage trucks mounted on the X rails.
Eight M6 x 20mm screws are used to secure the plate to the trucks.
There is not a lot of complexity to the X carriage. Next we will be adding the X drive system.
