I've just received my Ender 3v2 and tried multiple SD cards, all have been formatted to FAT32 with no luck. Under the Print selection, all I get is the back button. I looked and I have the V4.2.2 and the firmware is up to date, Showing 1.0.2 unless this is not right and this is why I'm having this issue. Even when plugging directly into the computer, nothing is showing up.

    $\begingroup$ Format them as FAT16. How big is the card? $\endgroup$

    $\begingroup$ Pretty sure FAT32 works fine. Only exfat or whatever latest junk MS is pushing is a problem. This sounds more like a hardware problem. $\endgroup$ Mar 31 at 15:06
  • $\begingroup$ We assume your SD card matches the reader as far as HD, xD, etc. SD cards that are too large can be a problem. $\endgroup$

  • $\begingroup$ 1.0.2 is Creality's unique version/branch of Marlin that they've created. It's a branch of Marlin 2.0 so that is totally fine and compatible with a 4.2.2 board. If you've ruled out cards, it may well be the reader. Can you use something like this to test if you can load files from SD cards using the USB port instead of the reader? $\endgroup$

  • $\begingroup$ The most recent card is 16gb but I also tried 8gb. And it is a miroSDHC I have not tried using anything to read through the usb port. I'll try that as soon as I can. I'm hoping it's not a hardware problem. $\endgroup$ Apr 1 at 1:20

What helps for me is re-inserting the TF card several times. Indeed, the machine has some trouble reading it, strange because this would seem to be an easy problem compared to the overall design of the printer....

Format for 32 with MBR for ender 3d I had similar issue. Check Reddit

    $\begingroup$ Hi Browset! On the stack exchange, we want answers to stand for themselves without needing to navigate around to other places on the web (link rot, convenience, etc). This has the makings of a good answer but could be improved by detailing the information you reference here and clarifying what MBR is. When you get a moment, you should take the tour and read more about the stack exchange format in our help center. :) $\endgroup$

    $\begingroup$ Check Reddit? Where on Reddit? Link? What if the link to the Reddit thread dies? Please edit your answer and provide details to the solution, in the answer, as well as a link to the source for your data. $\endgroup$
