Well, now the fun begins. I'm starting to have bed adhesion issues and some other anomalies at the start of the print.
In some cases, I've seen the first layer or so simply start to lift at some narrow edge or corner. If a small amount and there is enough buildup, the print can continue with a minor defect. But usually, the head will come across and hit the lifted section. Other times I notice a small fuzzball or artifact mysteriously appear almost immediately. After that, the nozzle will hit that and break that section free of the bed. I haven't figured out what's going on there as it's almost impossible to focus on the nozzle when it's that close to the bed. I almost want to say I see some plastic curling up around the nozzle that eventually sticks to the part, or other times it looks a piece of the plastic just curls up from the part layer.
Maybe I am experiencing the issue with the bowden tube working its way out of the head because of poor quality tube and quick connect fittings. Also, the center of my bed is getting smooth due to the scrapper and trying to work the finished parts off. The bed had immense grip on the first prints - it was too good! That was certainly a better problem than what have now, so I was thinking of a way to restore some of the texture. I may also get a thin piece of glass or mirror and have it coarse sandblasted. Maybe I'll keep one smooth for variety.
Another question, if bed leveling, or rather, Squish is so important, how is that addressed when printing thin layers? Is that done by the extrusion rate relative to linear motion? I might have the nozzle too close as I usually use a skirt adhesion and it is typically much flatter than anything like a D shape, but I am also using thinner layers than when I started out. There are so many settings it's getting hard to remember what I did and changed. Cura does provide a list of deviations from the default settings, however. Time to start serializing these combinations and marking the prints.
I finally figured out how to get "vase" mode by selecting Spiralize Outer Contour under the Special modes...
