I am just getting to Cura - 3.04 or 15.04 - not sure why there are 2 numbers for the same thing??? I want to view my sliced model layers from bottom to top, but I get only top to bottom. How do I change that?? ALSO, Is the How To for 2 to be used with 3? I assume it is cause there is not very much under the 3 how to. thanks bill
