Good to know that PETG will always sting. I think the retraction could be adjusted and I have not yet messed with the coasting nor do i really understand that until i google it here in a second.That's pretty damned solid. Areas that could use tweaks (but I probably wouldn't bother):
bottom layer, small separations between the border and the fill, a little bit of peeling at the bow of the boat. Peeling can be from a draft cooling that section, but it could be the bed heat.
Little nuggets on the roof where the print layer stopped and the extruder lifted (visible in the 1st, 3rd, and 7th "step" from the left in the top down picture.) Coasting setting might help that.
Second pic you posted, looks like there may be some delamination on the front of the cabin, starboard side. It could be the picture, but it might be delam. I lean towards the pic being at fault as it doesn't seem to show up in other places. Delamination has a couple causes, usually not enough heat in the extruder, or a clog or so in the extruder. Based on the rest of the print I don't think that is the case here.
You can tweak and tweak and tweak till it looks perfect, but I don't think the time investment is worth it. I'd focus on getting rid of the stringing (should be able to get PLA down to nothing, PETG will always lightly string) and then just start printing.
I am not running the rig in an enclosure yet, that will be printed this weekend.
Thank you for the advice!
