What is the step height for the Taz 5 and 6?
You may think that a lower layer height is always better. 0.05 must be better than 0.08, right? The problem with this is that stepper motors move in steps. These motors moving in parts of a step can be a big problem over time. Less accurate layers will result in big layer lines and weaker layers.
What is their stepper motors is geared to?
What is the smallest layer possible?
