I’ve been trying to print the Make Shootout test objects. I’ve been using Cura for slicing, with the profiles from Lulzbot, 100 micron layer height and 50 mm/sec speed and Shaxon translucent blue filament at 200C.
I’m curious about how to improve results on the following test pieces:
(1) Fine Positive Features has lots of stringing at the tips of the spikes. I’d really like to know how to get rid of this.
(2) Bridging does OK, but not great. Curious as to advice on to how to get really good results.
(3) Robot: 1 hip joint and 2 leg joints fused.
Also curious as to why the Lulzbot profiles have nonstandard default layer heights, like 140 microns, 210 microns. Is it just a reflection of multiples of the minimum 70 micron? Or is there some reason it would print better at 140 than, say, 100 or 150?
