About this 3D model
The three layers are 5mm, 15mm and 20mm. they are measured then a proportion is found. These are then averaged to find the required proportion of the current steps. example: a = lowest step b = mid step c= total height d = desired proportion [(5mm/a)+(15mm/b)+(20mm/c)] /3= d this will then be multiplied by the original setting (if still stock, in sprinter, equals 2560) in your Arduino interface.
