You would think this to be true, but sadly Prusa can’t find the serial numbers to customers who purchased MK1 and then upgraded throughout the years to a Mk2.5s. Even worse, then make no effort to either provide a new one, or assist in added the SN to the SerialID on the Rambo USB port. Best I can tell, they see PrusaLink as an annoyance! I’ll be reloading Octaprint and selling this Prusa, onward to Bambu

Same problem here. My mk2.5s started as a mk2 and was later upgraded to 2s, 2.5 and 2.5s.

All methods suggested both by support and on the web yield the same result: a serial number that doesn't follow the required format and is thus not accepted by PrusaConnect. The number is always the same so it’s consistent and I’m very confident that it is indeed the SN.

Support assured me they would look into it and get back to me but it’s been 2 months now, with no updates.

I have the same issue. With the latest firmware 3.14 and prusa link tried the fake serial number function, but it does not create any SN. Do you have any solution how to use the prusa link with mk3s without a serial number. Thank you.

I tried using the "Fake serial number" option but it is still not populating this. Any suggestions?

To get the serial number in the board (if there is one), run

lsusb -v -d 2c99:

with the printer connected and turned on. The serial number should be on a line named iSerial

I cannot say more. The way your case should be handled is - support gets the order number from you and somebody figures out how to give you a new serial number. Then you'll use that. I'll ask about this when I get to Prague

any update on this? i tried talking to the support guys as you recommended. They tried to help, but were not able to. They pointed me to the hidden "experimental" menue to activate fake SNR, but this is only available on MK3. They wanted to check this internally and get back to my with a soultion via email, but i havent received anything.

if you know how to manually get the snr out of the usb i can try that, linux is fine for me. but i think there is no snr, because i had to replace the rambo mini board and ordered directly from ultimachine (was not in stock at prusa shop that time).

you almost certainly have one. They get stored into your prusa account and are sent via email
