I am trying to print a part that is essentially a thin tube with a slot in it. The tube has about 0.025" thick walls on it and I am printing PLA. The issue that I am having is 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!
