I am curious how you are getting 10 micro-steps?
You would need 5-coil stages to get that from the controllers I know of.
Normally, there are 4-coil stages, and thus four wires, two paired sets (A,B), yielding the 4-coil stages. (+ -, + -) (- +, + -) (- +, - +) (+ -, - +) repeat.
That is single-step operation or 1x.
Then there is half-step, which uses 1/2 current between each phase-switch.
1/4, 1/8, 1/16... etc.
I wasn't aware there was a 1/10th step controller. (Would that be the "metric" of controllers? Sounds interesting.)
Does it let you select individual steps? 10/10, 9/10, 8/10... etc...
