trying another card--its booting up and warming-- fingers crossed. If it does this again now, its got to be something with the printer

I have seen issues like this on computers using cards that were cold when inserted but heated up over time, after insertion, causing disconnects. The kind of intermittent issues that would cause any sane person to think they were cursed. If shorter prints work fine and longer ones do not, both from the same card, it is possibly a heat over time issue.

Other things that can cause this type of behavior is dirty power. Lights flickering, same circuit as the kitchen microwave, etc. drops the usb type connection almost immediately.

its clean power in another building--I'm an electrician, so its not a power issue for sure. really hoping its the cards. I have been running 12 to 14 hour prints as of late

Found this and many others on reddit. 2 Takeaways from this, 1)seems a lot of folks destroying many cards in this same printer, some reporting card is so hot it burns them when removed 2)some get this error but the print finishes anyway. Def a call to support:

If the issue is heat at the reader, add some serious fannage and a great heat sink and see what happens.

Thank you for this.. Good reading. I was looking for something like it but didnt find

found this they have some legit advice on high heat card options but definitely add some cooling too at the reader

I just saw the posts about SD card errors. I have see similar problems from two separate causes. First is bad contacts - on the SD cards themselves and/or the SD reader in the printer. In this situation cleaning the contacts may help. Q-tips with alcohol (since you probably already have is close for cleaning your print bed). Or a mild abrasive, like a pencil eraser can clean the exterior contacts. If all cards have this problem, it is more likely the internal contacts. Again the Q-tip approach might work. Cleaning the inside can be more difficult but a thin sanding stick (like an emery board might work. The second cause is wear and tear on the reader's entry "rails". With a lot of insertions and ejections the SD may no longer align and connect properly. For me this happens quite frequently when inserting the card. It does not register the card as even there, invalid, or unformatted. I have to "wiggle" the card around to make proper contact. I have not had this issue in the middle of a print but vibration could cause this issue on my machine - it is that sensitive to misalignment.

Hopefully its just the cards
