I noticed that when printing holes/cavities, I almost always get this kind of artifact (see picture below). It propagates for the whole length of the layers. I’m not even sure if it’s a hardware or software issue?
Also, this print was made using the PLA-fine lulzbot profile, but I feel that the print quality could be better … did anybody come up with an “ultimate” profile to get better results ?
(PS: My setup is AO-101, Budaschnozzle 2.0, 0.35 nozzle, PLA from filaments.ca)
I would bet a hardware issue, most likely the X and Y bushings. I am going to switch to Hardened steel Linear rods and Linear bearings soon and I’ll let you know if it fixes it on my Taz 5
