RE: 5 head semi/assembled shipping window?
@Jeggo:
Seems that the order number is a usual number of the Prusa ordering system. So normal orders as Prusament or spare parts get also a number out of this system. So it would be nice to start a new thread with the ordering data like this:
To append to my previous comment:
- Confirmation date: 4:13 pm GMT Thursday, November 18 2021
- Original Order: 5 Head Semi-Assembled
- Order no.: 1637251XXX
- "Almost Ready" email - N/A
- Delivery date: - N/A
My pre-order confirmation email for my 5-tool semi assembled arrived at 4:13 pm GMT Thursday, November 18 2021. I thought I was pretty quick to get in line. I have not yet heard anything about my order being fulfilled.
RE: 5 head semi/assembled shipping window?
- I orderd on 18.November 2021 15:15 (1 Head semi) Order Nr. is about 1637248500 +/- 🙂
- the "your order is ready" mail came on 29. june 2023
- I was able to switch from 1 to 5 head on 18. september (until then it was not possible), paid the same day
[...]
- The package was collected today by DHL
With my order number ~3000 after yours (My #: 1637251XXX), This gives me hope. Thank you!
3000 XL's is a lot for them to make, but it's nice to be able to put a number to it. I'm aware that order numbers also include non-xl orders, but I find it likely that most orders made in that time-frame were for variations of the XL.
RE: 5 head semi/assembled shipping window?
The ordernr is a time stamp. Its not counting up. So you could have +3000 and only 5 orders in between
RE: 5 head semi/assembled shipping window?
And for all my bitching, I finally got the 'switching'/completion email last night. Paid it and got an email confirming the payment. I've got some travel in the next two weeks, so hopefully it will be on its way to me by the end of the month.
OK, my order number is 16372452XX. I think this is the only really relevant number. I can understand that people don’t want to reveal their order number, but frankly, the last three digits are not that Important- a few minutes at most. Just anonymize the last few digits.

So my order is 2:20pm ish. 5 head semi. Last week they said it would be weeks before my order would ‘switch’.
Sounds like I’m getting screwed…

Yes, the order number is the Unix time stamp. https://www.unixtimestamp.com/
RE: 5 head semi/assembled shipping window?
yep, which is really dumb. So how do they avoid two(or more) folks ordering at exactly the same second? As a software developer I'd never rely on that not to happen especially if you sell a popular product! Can you imagine if amazon did that? Most real systems us a long(e.g biginteger, unsigned 64 bit number) sequence number, or a uuid for such things. I typically use postgresql, and I think I figured it out once and a bigserial(sequence back by a biging), you could increment the number every nanosecond for 267 years before it wrapped around lol.

RE: 5 head semi/assembled shipping window?
Unless the system is designed on a FIFO order queue. Comparing it to Amazon isn’t exactly fair, 2 totally different operations with Amazon being a logistics company first, and a retailer second. Amazon also has to have an inventory management function to prevent ordering product that is out of stock.

RE: 5 head semi/assembled shipping window?
Well of course, we just don't know when the order number is assigned lol As you mention, ordering systems have to deal with inventory scenarios like two folks ordering an item that has a quantity of 1 and the second one has to be told the item is out of stock. But the point is that 1000 people could in theory click the order button at the same time and they could in theory(depending on when the order number is assigned) get the same number. Whereas if you select the next number in the sequence you'd be assured that each of those 1000 people get a different number. This would be similar with a uuid, which is of course the whole purpose of a uuid. Clearly they've considered this and handled it. I've often wondered though if some of the crazy things like folks ordering on 04/01 getting their order before those who ordered on 03/28 is caused by edge cases in how they assign order numbers. Not knowing what system they use for ordering, I can only speculate. I assume(hope) it's not as simplistic as that lol But given they still use wordpress and php for the forum, it's hard to say lol

RE: 5 head semi/assembled shipping window?
Anytime stamp system will have the potential for a conflict. Amazon would have what, a 1000x or more orders?
Obviously it works. Bumble-bee syndrome.
RE: 5 head semi/assembled shipping window?
yes, which is why in super high volume things like message being consumed on kafka you're typically dealing with UUIDs as identifiers instead of sequential numbers.
SQL databases have managed to use sequences for decades. The tradeoff there is a small lock to ensure that two requests to get the next sequence number are serialized. Again, I assume this is not an actual problem in prusa's ordering system, but as a developer who writes applications that do db things, I just wonder how they are doing it lol. it would be like one magician watching another magician and trying to figure out how he does his trick 🙂

Edit: delivered today. DHL was pretty quick.
I took DHL economy (3-4 days) 34,07€ but got 3 packages (extras i ordered).
It took DHL 2 Days from (real) pickup to Germany.

RE: 5 head semi/assembled shipping window?
Look forward to hearing your thoughts on it.
RE: 5 head semi/assembled shipping window?
Print quality looks terrible here. worries me as I finalise my order.

RE: 5 head semi/assembled shipping window?
Yikes! Hopefully he just missed a step somewhere. for the extra 500 bucks I'm not looking forward to do that much assembly, oh well. I've bought all my printers assembled to feel like I've had an assurance it would work right out of the box. I get that the size of the box would be even bigger if they assembled it with extruders, and the jostling during shipping would probably wreak havoc on an assembled unit.
I'm going to think positive and think his experience was a red herring.

RE: 5 head semi/assembled shipping window?
EEK!
I can only hope this result was due to a overlooked / incorrect assembly step issue or a one off manufacturer error. That looks horrendous even for a $100 printer
RE: 5 head semi/assembled shipping window?
yep, my hope as well. I'm sure with duty etc this is gonna be a 5k+ investment and I'd be none-to-thrilled if that's what my first print looks like lol.

RE: 5 head semi/assembled shipping window?
I am not defending Prusa here, but uncontrolled experience/experiment by individuals does not actually amount to much. Note that this was not a live recording but edited.

RE: 5 head semi/assembled shipping window?
I agree. Having just did an MK3S->MK4 upgrade, I can definitely say that I appreciate more how much is involved in crafting those instructions! It probably took me longer to do because I was deathly afraid of doing something wrong. But I was fortunately that after getting it all together it passed the self-tests first time! I have a second kit sitting here in the box and I plan to start the upgrade of my second MK3S this weekend and I feel a lot more confident about it. I could totally see that if you're not careful how things could easily be missed and render bad printing results. This is why I'm pretty confident that the quality in the vid is not going to be my experience. Despite Prusa really fumbling the whole pre-order/ordering things for both the MK4 and XL, I know that the machines will be quality, even if it takes a few firmware/hardware tweaks to get there.
