Hi Guys,
Just got this printer the other day, and I’m just having some trouble getting decent prints. For my first test-print I"m trying to print this guy: Westhighland white terrier by angry_elf - Thingiverse. Since I run Linux, I’m using OctoPi (much better than the official software, which I tried in a VM), but I’m struggling to find a good cura profile. I printed the first one using the default Cura profile for M3D PLA, and got this:

Not bad, but some obvious issues. First, some of what I think is called pillowing. You can basically see through the top layers. The strands are too thin across, and the gaps between the walls and the infill isn’t great. Overall, this is the best print I’ve had, and the only full one. Additionally the raft has some bad stringing, but there given the geometry of this print that isn’t really an issue.
The most recent print I tried with these settings. I upped the temp (slightly) and flow rate, and tried to make it more sensitive to retraction given the stringing.

And got this (just the raft, I aborted it after one and a bit layers):

Down the bottom right is the where it started, and I think it was coming out pretty flawlessly. Smooth, no gaps, really very nice and good. But as it continued to print, some issues began to appear. As it went to the top left, you can see some gaps appearing on the bottom layer. The top layer started okay (top left), but as it moves right things went downhill quickly, until it just stops extruding properly at all. At this point I aborted, and I now come to you for help. What settings do yall use for cura/octoprint/M3D? Is there anything obvious that I should change for mine? I’m struggling to find any definitive cura settings aside from the ones that came with M3D Fio. I’d really appreciate any help!
PS. Is there a G-Code for turning off the damn LED? It’s pretty bright, and I’d love to turn it off when I’m not using it.
