    leave behind a blob if lifting

    Yup, can confirm - I do however rarely print stuff that needs to be pretty, which is why I take the blob over the noise of hearing my nozzle drag over something (and/or potentially knock something loose). Also, “aligned” seams hide the blobs on a lot of prints.

    Edit: About those blobs: I think I just fixed them! I have a bowden-style printer and had adjusted “smooth time” from .04 s to .06 s previously - Due to the combination of settings I’m running now (Z-Hop + Wipe being the main culprits, probably), the blobs were not on the outside, but protruding upwards into the next layer, which caused nasty noises when the print head went over them. So I thought, why not crank that smooth time setting mid-print to see what happens? And I can confirm: At .12 s the blob is now basically gone. A tiny wisp remains, which can probably be fine-tuned away, but I guess that’s the magic setting I had to adjust for this issue. Iirc the consensus on this setting was “adjust a little bit for long bowden tubes, but it doesn’t really matter”. Ha!
