You don't increase "accuracy" by using any kind of reduction gear !!!! Fact is, you are more likely to decrease it because of the gear quality. And forget about printed gears, any kind of.
Digital Dentist used worm gear in combination of belts to replace lead screws for Z.
As for the statement above, using 2mm pitch and 0.9° motor, can you tell what layer height you use and what is the Z displacement for a full step ?

Oh, so what your saying is MORE steps per mm WILL NOT improve positional accuracy?

I have to agree with MKSA here: More steps will definitely not improve positional accuracy if the errors introduced exceed those already in the system. 3D printed gears are seldom of anywhere near the accuracy of machined gears. Backlash, even with the best gears, can introduce catastrophic errors.
