Hi!
I downloaded Karl's Ender 3 profiles for printing the FMC-CDU. After dialing them in for my Ender3 with some custom addons and printing a few of the parts I realized the profile had locked the top and bottom lines to 90 degrees. Normally they would be perpendicular to the one below. (45, 135) Now I guess my question is for @Karl, what is the reason for locking the skin lines to only go in one direction? Is it for print quality, to ensure different top levels are always printed the same way so it looks cleaner or is it for some other reason? I like that they are not going diagonally but I'm thinking of giving them the possibility to go 0 and 90 degrees. I find I sometimes get gaps that I normally would not get with perpendicular top shell layers, even though the final ironing pass is perpendicular to the last regular one.
I'd love for you to elaborate a bit on this setting and why you have them set at 90. Again, a million thanx for what you are doing!
Bonus Question: This picture above has a (to me) strange artifact. The outer side of the right side here looks very smooth but the inside of the same plane is rugged and looks under-extruded. It does not matter because this is the Backplate but I still would like to figure out what is going on.
