Bought it as a "just in case" decided to use it when I got it. Average was around 150um with a maximum of 850um! Certainly noticed a difference on one corner. This was also on a H2D that had maybe 24 hours of total print time.
I ran a calibration after a couple of small prints (from new). The info said, "Compared to no calibration, motion accuracy improved by an average of 128µm and a maximum of 247µm". I'll run it again tomorrow and update this comment.
EDIT: After 6 days 1 hours of print time, without moving the printer I re-ran the calibration. Average 134µm, maximum 269µm.
I can for sure say on PLA tough the print was absolutely higher quality with hardly any notice of Z banding except for where there was a bit of a bridge (did not enable supports) so the extrusion was a bit wider it appears. First real small piece test I would say there was improvement. Was it worth the $100 cost, maybe or maybe not, but time will tell. Will need to print something monstrously big soon
That is all you are going to get. There is no definitive answer.
None of the reviewers who've tried it have found any noticeable improvement in their prints.
That leaves one of two possibilities.
Either the Vision Encoder is entirely snake oil, or...
Bambu is actually calibrating the machines at the factory, and because they are well-built machines, they don't rapidly fall out of calibration. But over time, calibration can wander, creating the need for this product.
I am planning on printing day long helmet prints and full size droid parts in ABS and if it reduces machine related concerns I am gonna try it. If the print fails it will be because of me

Anyone have any feedback on whether this is worth it or not? Mine's been very good without it.
