What is the correct step/mm for the Openbuilds OX Z axis using a Tr8*8-2p 4start screw?

What is your microstepping set at?

1/8th
I think it should be 200 steps/mm, just wanted some confirmation.

You're correct, that's what I use on mine with 1/8 microstepping. 200*8 micro steps per revolution, divided by 8mm per revolution.
