I saw that I could not find my printer's profile in the Make/Model list. (Creality Ender-3) Therefore, I have not upgraded, for fear that I may not be able to print properly if I do. I guess I will wait until there are patches or fixes to the upgrade.
I am also having trouble trying to print an object that is tube shaped, but with thick walls. eg: a tube that is about an inch thick but has a hollow tube in the center about 1/4" wide. When I slice it, the whole object infills, including the hollow area. How can this be avoided?
