With this update your Z axis will be more precise and you will avoid common problems such as Z waving.

You will need:

• 2 x SWZ-063009 precision nuts (I bought them here)
• 2 x threaded rod 8x1.5mm (lenght 360mm) (I bought them here)

You will also need to modify your firmware, it's a simple line in Configuration.h but it's important because the new rods have a different pitch than the original ones. So, go to Configuration.h, comment the first as follows:

//#define DEFAULT_AXIS_STEPS_PER_UNIT {80.19,80.43,2560,458.3} // BCN3D+ default

And add the new line:

#define DEFAULT_AXIS_STEPS_PER_UNIT {80.19,80.43,2117.048,458.3} // BCN3D+ HD (precision Z rods from IGUS with 1.5 thread pitch). Theoretically it should be 2560/1.5 but 2117.048 was fine calibrated and outputs better results, I recommend recalibrate it for your specific printer
