Hello!
I try to print a one of the part for a company that is essentially a big tube with a slots in there. The tube has 0.035" thick walls on it and I am print different PLA. The problem is that I have the edges of the slot come out jagged, as seen in the attached photo. I’m printing at 60 mm/s and have tried extruder temps of 200C, 210C, and 220C. I’ve also tried layer thicknesses of .2 mm and .1 mm.

How can I get a smoother slot in my part? Thanks for your help!
