Received my core one today, not tested?
I got my core one today got it out of the box and put the screen on and when I started it up there was no firmware on it? That's when I realized there was also no test print either? Was this an oversight or is prusa not testing them before they go out now? It's doing the self tests now and hopefully there are no problems but I'll be kind of aggravated since I waited two months for it to get here and it showed up with a problem that could have been fixed before it was shipped if they tested it.
RE:
It does have the print out that everything was tested in the box so I guess it was checked.
Anyway, I just printed this benchy in 8 minutes (once it started printing) it's crazy to see it spit out a benchy that fast and it actually looks ok considering the print head looked like sonic on cocaine it was moving so fast. Maybe I never pushed my mk4 as fast it could go but this was way faster than I have seen outside of youtube videos.

Very good for a 5 minute bench. Some leeway in speed. Maybe you can get it down to 4 minutes 😉
Congrats on the new printer
RE:
oh yeah, where's my fish magnet?
All the reviews I saw made it sound like it comes with that?
RE: Received my core one today, not tested?
My Core One was also missing the firmware on the internal flash and had to download and install myself. If this had been my first Prusa I would have been very upset about the "out of the box experience".
I also swapped out the brass nozzle for an obsidian nozzle and while that process is straight forward and I have done so a few times on my MK4 and XL I am now getting nozzle cleaning failure messages when I attempt to print. 🙁
RE: Received my core one today, not tested?
You had to download the firmware? On mine it wasn't loaded, but it was on the included USB stick. I assume it was part of the quick start to plug in their included stick before first power on, which would have installed it.

RE: Received my core one today, not tested?
Well crap - I use my own usb stick and never inserted the Prusa provided stick. Stupid me.
RE: Received my core one today, not tested?
It does say in the instructions to use the included usb as it has the firmware on it:

Are you sure the nozzle is not loose?

They have one listed in the store at $99 but not available.

Not really good, remember drips of water erode stone, please slow down, and what's the hurry, unless you do not have enough time to boil an egg, hard boil that is.
A very bad example of "Benchy".
Disappointing in reading the necessary requirements of loading the software, this side of it should be plug and play, glad you are savvy, else I would be sunk.
You waited 2 months for a top of the line printer and when received then you had to tinker with, Shame on Prusa.
keep us informed, certainly the Prus CORE ( a long time in development) is not on my purchase list, for €600 you can get a Bambu, next day delivery, Sadly i think it´s a case of monkey see, monkey do. good luck. And for those living outside the US, the EU is in for a Trump review of tariffs.. We shall see. get the US RUST BELT up and running.
RE: Received my core one today, not tested?
You may have missed (or ignored) several other replies. The firmware is included on the USB stick that comes with the printer, and the instructions say to plug that in before powering on which will install the firmware and get you the test files. There's no "tinkering" required.
Maybe it's easier for them to leave the firmware blank in case they find a problem after hundreds of boxes are packed, they can just replace the USB sticks without worrying anyone will unbox a printer and start using it with bad firmware. Or some other streamlining of the packaging process.

RE: Received my core one today, not tested?
The problem with the nozzle cleaning failure was that the PETG I was using had a bit of filament creep on the end of the nozzle that was pressed into a pancake on the nozzle tip. That pancake caused the cleaning to fail. There is a long thread in this community that details the problem. So I need to do a better job of making sure the filament creep is removed before starting a new print.
Regarding the Prusa provided USB stick - they all have slow read/write times so I just immediately replace with one of my own.

But how would Prusa do a final factory test of the printer without having firmware installed on the STM32 processor? The test must certainly include driving the printer from its own xBuddy board (so that board and all its connections get tested too)?
RE:
Hey, I don't know for sure if they tested it, but if we assume they did considering past printers...It looks like all they would have to do is do a hard reset after testing which would wipe the firmware from the board.
"Hard reset (USB with FW needed) due to the complex partition layout, the firmware stores its settings not only in the EEPROM but also on the XFLASH. In some edge cases, it might be necessary to delete both of these. Once this reset is done, the user must insert a USB drive with firmware as some parts of the XFLASH will be created again from scratch." - https://help.prusa3d.com/article/factory-reset-core-one-mk4-s-mk3-9-s-mk3-5-s-mini-xl_421206

In my understanding the Hard Reset will only reset the firmware settings (parameters); it will not reset or delete the firmware itself. But it is possible, of course, to delete the firmware from the STM32 via its bootloader and one of the processor's programming ports.
Maybe Prusa do install a special alignment & testing firmware during production and remove that again after the final test? But they should definitely install the user firmware afterwards: They have advertised the smooth out-of-box experience, and letting the user install the firmware would certainly be a step in the wrong direction. I guess this was simply a glitch in production -- maybe a new technician who was not fully up to speed yet, or someone who hauled a few printers over to the packaging area before they were fully completed?
RE: Received my core one today, not tested?
Ok, reading it that way, maybe the hard reset doesn't delete every bit of the firmware, but since a USB stick with firmware is required to use the printer again, how would we know if there were firmware left either way? From the user perspective it seems equivalent to there being no firmware at all. The description sounds like the partition map or some such is deleted or otherwise rendered unusable.
To me, it seems perfectly logical to have a completely fresh firmware (or at least, firmware partitions and settings) installed on every printer once removed from the box. I don't see inserting the USB stick that comes with the printer as harming the out of box experience any more than having to install the LCD screen or insert the power cord.
But I guess we'll see as more people receive the printer, as yes people who have them now have early orders. Mine came this way where it installed the firmware on first boot with the USB stick.
