For some reason when I print tubes it leaves a bad z-scar. When I print any other parts the prints looks flawless. I can try the random start point but I don't want to have marks all over the part. I found other threads of people having the same issue but with no solution; maybe there is glitch with the software when printing circular tubes.
I am trying to print an intake for my car. Currently I am using PLA but I am going to get some thing more exotic so it can take the heat. Any suggestions on what material to use?
As you can see the intake looks really good other than the nasty z-car.
