You can use the barrel connector on the Arduino to keep it powered.  So get 
a 2.1mm x 5.1mm connector, tip positive plug.  Then wire that to your 12V 
step down converter. 

If you're lazy and have Amazon prime, they have a 10 Pack with screw 
terminals for $6 meant for CCTV cameras

figured it would be the same with shipping any place else. Maybe I can send 
some out with stamps?

As for the PanelMax, can't help you there.  I have the reprapdiscount 
version.  There were quite a bit of changes I had to make.

I did figure some of it out by looking at Tommy's Panelmax blog:
