In case you need convincing, this is how the first layer of the calibration print went down:
Not sure if you can tell, but really none of them went down right.
Nonetheless, here is the final result after the full stack of layers was printed:
You can ignore the bottom row in the second photo, because I did a real-time “skip” when it became apparent they were likely to fail.
And this was the result of my trying to do a “perfect first layer” test:
Far from perfect: z-height was weigh too high. You can maybe tell from the photo because you can see all the way through the print onto the build plate almost a bit like looking through a Venetian blind. Also, when I pull it off the bild plate, each bead of filament layed down separates into their own separate strand. I could provide a photo of that as well if no one gets the gist of what I’m saying.
Hopefully someone reading this has some worthwhile suggestion on what to do. This has been enough torture for one day, so I’ll wait for replies.
