I never attached a scope on 297 output .. but I imagine if you clock it manually and look at output step by step ... 297 don't do micro stepping so the signal should be clear .. might be easier to debug the output if you use full step and not half step settings.
you can use a 3pin switch to clock manually outter pins to vcc and gnd, middle pin to clock pin on 297
