Im using sunlu silk pla, ive never had issues with the print head hitting things, and with leveling the bed to z axis during the bed leveling process, im not sure what you mean by z bar leveling. I level the bed before every print with a sheet of paper, or at least verify its still level.
ive tried 65, but 70 just seemed to work better.
20 % infill
1.2mm layer height, and my first layer squish is set during leveling, and i also always verify that the first layer is adhering by running my fingernail across it as it goes. usually just the skirt though, i try not to touch the actual part.
the printer is sitting on an old oaken dresser. its not wobbly and pretty stout.
even though in cura its set to have part cooling at 100%, the cooling fan doesnt come on(i didnt have any issues with it on other prints) but if i do into the settings while its going, i can manually turn it on. the dresser the machine is on is in a bit of a cubby hole, so i dont BELIEVE any air is getting blown directly on it
yes, there are only two lines of the 308 insert that are the bottom layer for the 308 insert. Ive included a snapshot of cura showing it.
