Teaching Tech has a video which details the process of using the original Step Test model at around 13:27.  However for this model, set the slider to 1.00mm for the Black, instead of 1.04mm, then set the other color to the maximum height.  Your filament change height should also reflect the 1.00mm instead of 1.04mm
