To do it more mathematically: *Math mode on* For a nozzle size of 0.4 mm you need to calculate the area of the nozzle: (Pi*d²)/4 = (3.141*0.4²)/4 = 0.126 mm² After that you need to decide (or test) which amount of material is need to compensate the under-extrusion at the beginning. Therefore you have to multiply the length of extra prime. So for DaHai8s 0.064 mm³ it means that you have an extra amount of approx. 0.5 mm *Math mode off* Hope that helps everyone who is finding this thread, like I do ;-) *waiting for applause*
