Try turning the motors by hand when powered on, they should be stuck and not move easily.
If they can still be moved, the enable is not set or wired properly. For testing you can disconnect the enable wires.

Since these have a TB6600 and added optoisolation you might try 10000
for steplen. If this does not work you might try single ended drive:
7I96 +5 to step drive +pul and +dir
7I96 -dir to step drive -dir
7I96 -step to step drive -pul
for steplen. If this does not work you might try single ended drive:
7I96 +5 to step drive +pul and +dir
7I96 -dir to step drive -dir
7I96 -step to step drive -pul

That may be expected until homing is setup and working
(and it doesn't look like any tandem axis homing is setup)
