Hi @my3DBr,
Well, the nozzle in general is important -as many other parts of the printing process.
I do not know much about "double/multi" channel nozzles, but for sure they are made to improve heat transfer to the filament flowing through the nozzle and this in order to print faster.. Higher speed will always degrade precision by some degree.
I'll think that if you want to have precision, you have to use the original nozzles and use the advised settings -"engineer setting".
How did the test go?
Thanks
Torgeir

Almost. Cura calculates the total extrusion for the entire line. The print speed is irrelevant then. Correct! I don't know what Repetier does with it. They work with CuraEn

Indeed Cura doesn't have any such modelling. And neither does the firmware. All things in Cura related to this, such as coasting, involve compensating measures to counteract the effects of the pressur

Thanks for that @ghostkeeper, again really useful information.

Woooowww @Torgeir, you just said something very very interesting.
You see, I installed the 3D solex kit matchless of heat block and the nozzle.
I noticed something when the printer does the initial purge of filament - it don’t fall down 90° normally. It travels like to the side first. As you know this nozzle has two internal channels.
Could it be it?
Unfortunately I started to notice accuracy problems before changing it, recently. But never worried too much before.
I will send come pics.
