The Z axis is driven by a Nema17 motor with a 3mm pitch leadscrew on a 2:1 reduction gear. The Z Axis has a step resolution of 0.00046875 mm (0,47 micrometers).
Suggested Layer Heights
Helps you to select layer height in a way, that Z axis moves only by full step increments. Z axis isn't usually enabled during inactivity. If the axis is disabled during micro-step, axis jumps to the closest full step and intorduce error. This effect is occuring to some extent even while leaving the Z axis motors enabled. This is most usefull to machines with imperial leadscrews but also for unusual layer heights with metric leadscrews.
Suggested layer heights for optimal quality ,using Microstepping, are:
|0.1 mm (100microns)||0.1003 mm or 0.09984 mm|
|0.15 mm (150 microns)||0.1505 mm|
|0.20 mm (0.2 microns)||0.2002 mm or 0.2006 mm|
