RE: QR codes printed on Prusament filament don't work

I have read that several people have already asked about it. I do'nt use Prusa filament and can only recommend contacting the Prusachat.

The QR code just contains the spool ID as shown in the photo

While a true fact, it sidesteps the issue: The QR code doesn't work. When you scan it you are not taken to the prusament website. Scanning the QR code on the box does work.

One of the features of Prusament is that you can dump a partially used spool on a scale, entire the weight, and it will [closely] estimate the amount of filament remaining. Thus, the QR code on the spool is more important than the one on the box, because half-way through the spool you may not have the box, but the QR code on the spool is still there.

It seems that this feature is broken, and that Prusa should address it.

RE: QR codes printed on Prusament filament don't work

Taken from QR-code-generator.com:

"What is a QR Code?

The QR Code is a two-dimensional version of the barcode, known from product packaging in the supermarket. Originally developed for process optimization in the logistics of the automotive industry, the QR Code has found its way into mobile marketing with the widespread adoption of smartphones. "QR" stands for "Quick Response", which refers to the instant access to the information hidden in the Code. QR Codes are gaining popularity because the technology is "open source", i.e. available for everyone. Significant advantages of QR Codes over conventional barcodes are larger data capacity and high fault tolerance."

Nothing in that description promises a web site address. I understand the QR code on Prusament spools does not meet your expectations - but that does not mean it is "broken" in any sense. Submit a suggestion to enhance it.

RE: QR codes printed on Prusament filament don't work

Do you honestly think this is a useful posting?

One of the advertised features of Prusament is that you can scan the barcode and go to a web page that will tell you all bout that specific roll of filament. One of the more useful features is the ability to determine the approximate length remaining on the roll. Scan the QR code, goo to the website, enter the weight, and get the remaining length.

Of course, obviously, a QR code can be used for any data encoding purpose. I don't think we need a lesson on this any more than we need the meaning of the word "word". But the advertised main feature of Prusament spools is the ability to get spool specific information from the barcode

From Prusament.com:

And, in case you really feel the need to define the obvious, here is one for you:

Definition of "Word": (Which is about as useful as the definition of QR code.)

That pretty well sums up this thread starting with the 1st post. Specifically, the prusa.io web site servicing the codes is down. Could be for a variety of reasons, including their hosting provider. You can easily call up the Prusa website and enter the number if you need it that urgently. The advertised ability to check the spool numbers is working fine. The ability to scan the code on the box is working fine. Nothing is missing.

"Just scan a QR code on the spool"

Perhaps somebody at Prusa should just read this and fix the problem, rather than us debating whether it should work as advertised or not?

Obviously it should work. Without knowing the details of why it's not working, we can only speculate about why it hasn't been. Prusa obviously invested some time and money into the feature, so want it to work. If you truly need the information, it is readily available by scanning the box instead of the spool. You're the one going on about "inattention" (including in the legendary PETG thread). It should be fixed. Let them know. Meanwhile, most here are here to help others and your trolling is not helpful. Griping at us does no good.

Ah, so what I hear you saying is that I should not expect Prusa to be reading these from postings and they are not an effective way of communicating problems with Prusa.

Fair enough. I had assumed Prusa followed their forums closely (like most companies) and that this was the preferred method of communicating problems to them. Most companies request that you post issues on the forums, and not through their technical support department. I have been told countless times by technical support at other companies that suggestions, and general problems should be posted on the forums and that this was the best way of reaching the engineers.

I hardly anticipated that posting this feature-flaw on the forum would result in being told that the feature was (a) not advertised as advertised, (b) not important, and (c) that Prusa would fail to see the posting.

Of course I can do math, and of course I can estimate remaining filament length the same way I have done in the past. I was just hoping that I would be able to enjoy an advertised feature.

Like the Prusa MMU2, there is a "reality disconnect" between the advertising department and what the customer gets. I like the i3 Mk3 printer. I would like the MMU2 if it reliably worked, especially on things like Prusa-sold PVA+, and if it didn't require so much fussing. I like Prusament, but I expect to receive what is advertised, including all 1kg and the advertised features as well.

I am less tolerant than most of being short changed, over charged, over sold, or under delivered. In return, I promise to be a fair customer and not play games. A square deal is a fair deal.

If it only worked as advertised.

RE: QR codes printed on Prusament filament don't work

Scanning the code on the box works fine. Scanning the code on the spool does not.

If you really need the information, you have already been provided the necessary information multiple times.

Instead, you have chosen to spend your time and waste ours trying to antagonize community members who volunteer their time to earnestly help others. What you are is readily apparent in this thread and others. 

RE: QR codes printed on Prusament filament don't work

The most sensible thing is to communicate the topic with the manufacturer. The Prusa community cannot change anything.

RE: QR codes printed on Prusament filament don't work

Bobstro:

Of course. I thought I was communicating with the manufacturer by posting to this forum. As I already indicated, most manufacturers prefer the use of forums as the venue of preference and monitor their forums.

Don’t blame me for antagonizing you or wasting your time. You are the ones continuing this. You could have just left my posting summarizing the problem. (The one with the QR code advertisement circled in red.)

You state that you want to feel you’re being helpful. Reread your postings on this thread and you’ll realize that you have not been. The first reply was missinformation. Most subsequent posts were more bullying, antagonizing and arguing with the question. They were certainly not problem/solution focused. Even your immediately previous message was more about attacking me than being problem/solution focused. Your responses are the opposite of empathetic; they could be classified as verbal abuse in a domestic environment.

Lets just focus on the problem: We have established that the feature is supposed to work and that it is broken and that this is not a forum that Prusa would be expected to monitor. Is there more to add about the problem/solution?

RE: QR codes printed on Prusament filament don't work

Classy.

RE: QR codes printed on Prusament filament don't work

If you do find yourself in need of help from the community in the future, I do humbly suggest you might want to change your ID.

The current one has established a certain reputation.

RE: QR codes printed on Prusament filament don't work

I am always interested in help to problems.

I do wish that there was a way to avoid these behaviors by others, as illustrated in this thread:

1. Misinformation. (The advertised ability to check the spool numbers is working fine.)
2. Arguing with the question. (Why do you feel you need to use this advertised feature?)
3. Tangental behavior. (I personally don't use Prusament and Definition of QR code)
4. Scolding. (You should know the things you don't know, and I am not going to gently teach you)

If the persons who post such responses choose to ignore me, it will make for greater success in the future.

I think an appropriate initial response to my initial posting could have been:

"Yes, this feature appears to be broken. This forum isn't monitored by Prusa. You need to contact them directly, not here".

That would have spared me this entire unproductive process. I have no idea why that wasn't the response, or why you feel that four types of responses outlined above are even acceptable. But no matter, we have gotten to the bottom of it.

RE: QR codes printed on Prusament filament don't work

If you would refrain from tossing in the "just one more case of inattention to detail" comments and responding with a condescending tone to responses from the volunteers here, you'll get a much better reception.

RE: QR codes printed on Prusament filament don't work

@bobstro

I think that is an appropriate and helpful suggestion. Yes.

I am quite frustrated with Prusa. I am a brand new customer, so this is all new.

I have had a long and frustrating journey with Prusa, the general theme being in attention to details on their part. Or, as I sometimes say: “The party must be as good as the invitation suggests.”

Thanks again for your last comment. You are on-spot with it and I concur.

[...] I am quite frustrated with Prusa. I am a brand new customer, so this is all new.

I can understand your frustration, and I think on some of your issues, that frustration is warranted. I've got my own gripe with the textured sheets, but my issue is with the product, not the people. Just be aware that we are not Prusa, and while Prusa staff do pop in here regularly, your audience is mostly just regular folks helping each other out. 

I have had a long and frustrating journey with Prusa, the general theme being in attention to details on their part. Or, as I sometimes say: “The party must be as good as the invitation suggests.”

Fair enough! I think you'll find a lot of people here willing to spend considerable time with you trying to resolve your issues. With any luck, you'll find fixes for your issues and be able to pass the help on to others. Problems do work their way up to Prusa, so your participation here is both welcome and important. I hope you get everything resolved and turn into one of the (mostly) happy campers.

Nice words, and I will take to heart and follow your advice, which was good and appropriate. Thanks.
