sfallan,
been down this road myself not so long ago, you might need to change your pin XYZ settings in motor outputs try them on X 2-3, Y4-5, Z6-7 if they dont work reverse them X 3-2, Y 5-4, Z 7-6.
Red cross all outputs for now.
Inputs all red other than E-stop green port 1 pin 0 for now.
motor tuning to start with try from left to right 1200, 200, 20. this is slow so you should not get into trouble, step pulse/dir pulse both 0 after try 1-1 up to 5-5

Try it let us know how it goes
