Wiring placed on a prototype board. Both axis move! 
I've run into problems initially, because the second chip wouldn't work no matter what I did but i finally found the issue. It was because arduino nano i'm using, specifically it's pins A6 and A7 𝗮𝗿𝗲 𝗮𝗻𝗮𝗹𝗼𝗴 𝗼𝗻𝗹𝘆 and to drive those chips, you need a digital signal. It took me an embarrassing amount of time to figure out and an unnecessary disassembly and assembly of the board. Hopefully this post will save somebody some debugging
