Issue seems to be following the seam when I rotate parts. in this particular example I am using 5% gyroid, if I switch to grid the defect is uniform along the part. This is just 2 walls, can't remmber infill overlap, I'll check tonight.

Yeah you're probably right...I'll take a looks at the motion system then

No, I've tried with that enabled as well, same issue. This isn't before a layer change, it's when it goes from extruding the walls to extruding the infill.

But even without infill this happens. It's the end of the outer wall that doesn't connect to the beginning of the outer wall and it's not really fixed by reducing seam gap, so I'm not sure what's actually causing it.

No clue, the heat completely numbed my tastebuds /s

Tried without PA but there was no difference, going to try different filament next.

As I mentioned somewhere else in this post, it seems to relate to the infill. I'm using gyroid, and the seam lines up with the anchor point for the infill.

I'm getting a 100% uniformly bad seam with grid infill, instead of the one in the pictures that kind of "switches side", which in guessing is because of the direction changes relative to the wall made for gyroid throughout the model, but grid always moves away from the wall at the same angle.

Edit: tried without any infill, same result as grid infill. So it's would seem it finishes the wall before it actually fully connects the wall-end to the wall-beginning on the outer walls, before changing to next layer or infill.

I just noticed, after intensely staring at my print from an awkward angle to see the nozzle while printing, that the gyroid infill has an anchor to the wall at the seam line. What kind of infill and infill settings are you using?

on-device processing is still a thing

Unfortunately even if this is initially processed locally, there's a significant risk that results and/or samples are still sent back. manufacturers have shown on multiple occasions that the allure of data they can leverage is too much to resist.

Nope, it's rock solid.

I did also switch to orca around the same time I changed the hotend...I'll give my old slicer a go as well, maybe it's a slicer issue.

This is just the basic cylinder that's part of orca slicer that I'm using to troubleshoot the issue because it's quick to print and the issue is clearly visible.

Yes I've already tried that, and it doesn't make much of a difference.

Yeah I've tried 190-220C, which is the range specified by the manufacturer of the filament.

I don't remember seeing this issue before the change, but I'm still new to the hobby and may just have overlooked or accepted it earlier.

This is the filament I've tuned PA with, and to my best ability this is what Elli's guide suggests is the optimal value 🤷‍♂️

But I agree, it does actually look like PA is tuned incorrectly and stopping extrusion too soon/starting it too late.

Randomised seams just spreads the issue out on the entire model surface, it looks even worse like that.

Yes, I recently switched the hotend from a proprietary one to a regular volcano hotend and did PID tuning.

It's printing at 200C with fan at 100%, using a 0.4mm hardened steel nozzle.

Yeah I've tried that, but it's still really bad, almost worse, with these scattered all over the surface.

3G has been turned off in a lot of places, but 2G is still very much used globally. It's still the last fallback for phones to maintain basic texting and calling functionality. In many places emergency services also use it for e.g. emergency information via text message.

No point in keeping the torrent if I no longer have the file. Unless it's something I know I will re-watch/use multiple times, I delete the file after I've used it.
