2 questions…
How do I change the nozzle size in Creality Print?
Does Creality Print use the Arachne engine?
Hey there @JimInWoodstock
Welcome to the Official Creality forum 
Glad you could join us and I hope someone here can help you… 
Not sure about question two but maybe if you click on where the arrow is and then on “manage” in the pic you can set up a profile for a different nozzle size… I haven’t done it yet.
thanks for sharing the solution
