The only thing I find on "teacup" is some form of firmware for rep raps? Do you actually have an Ultimaker or something else?

he does not have a UM. Anyway there are jumpers somewhere that specify double stepping or something. You could mess with that and fix it in hardware. Or you can fix it in software. For example build Marlin here:

And specify the steps/mm.

Or if you already have marlin installed you can update this parameter only (steps/mm for z axis) using only pronterface and gcodes. When you first connect with pronterface it will tell you the current steps/mm for each axis. You can change this value and save (you must save or you will lose the next time you power cycle).

For example M500 does the save.
