i just printed the one on the right and its surface finish is no where as decent as the one on the left with i did like 3 days ago.why those strange lines running horizontal on my print?it looks a lil like overextrusion since i did it at a high flow rate but even at 100 flow most of the time i get the same problem?to get a consistent somewhat decent surface finish like the one on the left is very difficult,what do you say
