it took me about an hour or 1.5 hours to move it from 2×2 to 5×5.
squaring it was easy (<5 min) and it worked the first time I powered it up..
but, I also didn’t have to unplug much and the existing extra wire I had hooked up let me go to 5×5.
expanding felt a bit rough (since it was new territory).
shrinking was simple because I had already made it larger and so the process was pretty familiar.
