Can anyone share experience with that?

I think we first need to agree on what qualifies as a ābig differenceā ā for some users, it will be worth it, and for others, it simply wonāt be.
If youāre someone who doesnāt really need the extra precision, it may not be worth it ā unless you just like knowing your machine is performing at its absolute best. Personally, even though I may not need that level of precision for most of my work, I still prefer to keep my machines as accurate as possible.
Will I actually notice the difference? Honestly, probably not in most cases ā but itās still something I value.
Iām still waiting for my H2D Combo Full Laser 40W to arrive, so I canāt give you any hands-on feedback just yet. But I do keep my X1 Carbon in extremely precise condition, and based on feedback from others and forum discussions, my unit seems to be performing at a very high level of accuracy.

Iām probably the only one who thinks that this plate should have been installed as standard on a 2.000 EUR printer 
Maybe directly as surface of the printbed ā¦ But āextra precisionā is something i would expect from a printer in this price segment

There are quite a few things that really should be included, such as the external filtration system for the laser option. But to be fair, not everyone will be willing to pay extra for that added precision, so itās somewhat understandable that itās not included by default.
However, when it comes to external filtering, itās more or less essential if you plan to run the laser at home ā and even then, it likely wonāt be sufficient unless you also vent the exhaust outside.
As for the HF nozzles, Iām honestly a bit puzzled as to why they arenāt standard on this unit. To me, that would make more sense than focusing on the added precision.
And no ā youāre definitely not the only one wondering why certain accessories arenāt standard, especially considering the price of the machine.

I see precision as standard for a 3D printer. The filter system, on the other hand, is absolutely not. Especially when you look at what good systems cost. I would never have expected that to be included.
I work with lasers, I have an extraction system that leads directly to the outside. So for me, for example, it would be wasted money if I had to pay for it with the printer.
But āBuy this printer for 2000,- and add another 80,- if you REALLY want it to be preciseā is a bit ridiculous

I hear you! 
Precision absolutely deserves the top spot, and they should go the extra mile to include everything necessary. I know the machine is factory-calibrated to match what the Vision Encoder reads, but like with any precision tool, things can shift a bit during shipping.
So yesāprecision first, everything else second. That said, for the laser version of the H2D, it really should be ready to go straight out of the box. Right now, it feels like many users who invested in the 10W or 40W laser arenāt necessarily adding an external filter or setting up proper ventilationā¦ and that could come back to bite.

Well, the Vision plate sold out immediately again. So it seems many users anticipate good value in the purchase.
I wonder of people with future H2D purchases are buying accessories in advance.
It wasnāt even available to buy before it sold out? I was watching online and it just went from available the 22nd to sold out. I am also signed up to be notified when it is available and never received a notification so I am not buying that it sold out in seconds.
It became available at 10am EDT. I bought at that time. I did not receive a notice of availability

Iām basically of the same opinion as you, ordered the vision encoder just to keep things in tip top shape. the extra accuracy will make screw together parts, etc just be that little bit nicer.
only difference is iām waiting for the 10W laser version

I noticed there were two different links to the Encoder the link I was refreshing has it sold out while another link from Reddit showed it available to purchase until I went to pay.
It was available for a little while. I ordered one at around 6:50am PST (oddly before they said it would be available), and checked again after 7am and it was still there. Maybe you had a cached site problem.
Iām not expecting too great of an improvement. I checked the accuracy earlier and I was very happy with it. So Iām not expecting perfection when I get to try it out. I am hoping it will improve accuracy of the inner and outer diameters of holes, but Iām not sure that is included in the calibration.
That saidā¦ I am extremely surprised to see it sell out twice quickly. Its a $100+ tuning aid, that is not really needed.
Hiā¦out of curiosity what do you do to your X1C to maintain precision? I maintain my X1C regularly (grease/oil, clean plates, routine calibration, etc.), but I donāt know what else I should do.
Iām waiting for my H2D and would love to keep my reliable X1C as precise as possible ā without something similar to the vision encoder Iām not sure what to do to max it out.
Appreciate any advice!!
More or less the same as you ā I keep track of my filament calibration. Even well-stored filament can shift over time, and that can affect print quality and consistency.

I ran the motion accuracy calibration today with the vision encoder plate. It told me my accuracy has improved as little as 234 microns and as much as 255 microns. Canāt remember exactly what the verbiage was, but those were the numbers.
So after running the calibration, my motion accuracy improved by 0.25mm. How much of a difference that makes, I dunno.

Does the vision encoder really need an Ā£80 metal plate?
Could the pattern be printed onto stiff paper for example (using a 2d printer) - a bit like you do when calibrating printers and scanners.
Failing that - could the calibration pattern not just be on the back of one of the normal printer plates or on the surface of the bed below the print plate?

Youāre absolutely right, despite this I ordered one yesterday.
Probably, but then it would be a hard sell at 115 bucks! I bought it by the way, lol.
I have a high end photo printer. I wonder what the precision is on that machine.
Bambu would need to release the file for us to print our own copy. But I expect that they produce the Vision Encoder on a specialized machine. I doubt they are price gouging on this particular item. I think its expensive to produce at the precision required.
Guysā¦ its manufactured down to a 5Ī¼m standard. That is very expensive. Jump on JLPCB, PCB Way, or the company of your choice and ask for a 5Ī¼m tolerance and a 0.1mm tolerance and see what the price difference is.
Sure, Bambu could have made it cheaper or created a printable option, but letās be real, that would have created more problems than it fixed. You know as well as I do, people donāt have the commonsense God gave dogs. And they would be calibrating the machine with wrinkled paper and Bambu would be spending 80% of their time troubleshooting user stupidity (which they probably do a lot of anyway).
Sorry, I know thatās pretty negative, but if you are on this thread, you know what Iām saying has a lot of truth in it. Sure, there would be some usable facsimiles, but it wouldnāt be worth it for me, so I can understand why they donāt want to touch that with a 10-foot stick.
Also, I assume the cost of entry is a ācost of supportā as well. So, in effect, if you are willing to buy a $100 calibration tool, they are willing to spend time with you trying to maximize it. Againā¦ You can complain about a lot of things when it comes to Bambu, but price gouging isnāt one of them. They have consistently come in under expectations.
