Parts printed... check. (2 kgs of PLA later)
Annoying sourcing of electronics (because I'm poor)... check.
Impatient wait for delivery of electronics... check. (good thing I made one of those spinner-thingies)
Local sourcing of nuts and bolts... check.
The hardest part of this build was deciding what I wanted for dimensions. I went for a 36" x 29" x 3" build area. This is large.
*EDIT* The hardest part of this build was figuring out the wiring for a series connection between two opposite-direction steppers. The instructions were strong, but my mind was old and weak. More on this later.
