This would be a sectioned off project like to tiling.
Basically, draw up and model the design at full size, then use a series of rectangles to define the area for each section.
For doing the model/design see:
The tiling may require some judicious arranging of the boards on the table and of the origin points in the file and on the machine. (I suspect you’d need to use all 3 along the left edge, and have a succeeding set of positions for the boards) — @fenrus did do a sectioning tool which might help.
