Creating a spare SD card

Hello
I need to create a spare SD card
I used sandisk formated as fat32 and the printer does not recognise it.
I see the SD card inserted message but in menu the is a no sd card message. Empty folder with no file although but i copied a gcode file on it earlier.
How do i prepare a sd card so it is recognized by mk2

Re: Creating a spare SD card

When I look at my SD card from the Prusa it's just an MS-DOS Fat 32 disk. Nothing exotic.

Hi,

Have you tried to use your operating systems own formatting? E.g. in windows right-click the card --> format --> FAT32.

Re: Creating a spare SD card

Did you ever figure out how to create a spare sd card? I am having the same issue. I have already formatted the card using fat32, but it still doesn't work. I am using a 64gb micro sd. Is there a size limit?

Re: Creating a spare SD card

Sorry I have never used a 64GB card,
could you try a smaller card?
my 32Gb seems to work ok!

Re: Creating a spare SD card

Mabye Marlin doesn't support more than 32GB.

This is often a limit for card-readers.

Re: Creating a spare SD card

I've had trouble with a 4GB card by the way. So I'm not sure if size is the only factor.

Re: Creating a spare SD card

😕 hi guys, have you ever calculated how many *.gcode files you could store on such big sd-cards ???
🙄 it's going to be very confusing if you store 50 or more *.gcode files at a single sd-card when you try to navigate through it, using the little lcd console.

➡ personally i prefer small sd-cards, like 512 MB ones... and i can still pack enough files on it to loose the orientation.

dem inscheniör is' nix zu schwör...

Re: Creating a spare SD card

I have a 32GB Sandisk Ultra Plus microSD card that works just fine. It is formatted FAT32. I did format it on my Linux laptop, but that shouldn't make a difference.

I do have issues with the MicroSD to SD adapter. My printer and computers will occasionally not recognize the inserted card. All it takes to fix that is to remove the microsd card from the adapter and reseat it.

I know 32GB is overkill, but it was on sale.

Indeed, but the bundled in card is 8GB. 😀

🙄 it's going to be very confusing if you store 50 or more *.gcode files at a single sd-card when you try to navigate through it, using the little lcd console.

Folders!

I put the bundled Gcode files into their own folders, then I have a folder for calibration files (eg. v2calibration, 1st layer calibration - similar to yours -, etc), and an Archive folder for Gcode that I may want to print again in the future (eg. I have some modular objects where I can print more pieces if I need too).

Re: Creating a spare SD card

I was having this issue. Finally I formatted the SD Card (FAT32) with the "Quick Format" UNCHECKED and that worked!!

RE: Creating a spare SD card

I had issues, with the card reader not working.  Turns out the size of the card was the issue.  64 GB, no go.  32, worked fine.

RE: Creating a spare SD card

Not sure if anyone is still having this issue but I was able to get my printer to read my card, 64 gb sandisk, by reformatting it as a FAT32. To format it as this I found a nice piece of free software, link below, that formats any size drive as FAT32. When you follow the link, click "Windows GUI version of fat32format" then click the picture and run the software. So far I have tested this on 4 new 64 gb SD cards by sandisk and all have worked.

RE: Creating a spare SD card

Hi

FAT32 should work without any issue. Just checked a spare SD 4GB card standardly formatted for FAT32.

What is the size of your SD card?

Check please your g-code file extension is correct.

@william-h14

Thank you for this hint! I was having problems with my 32 Sd card not showing up on the printer but after formatting it on my laptop with the quick format box unchecked, it worked!

I have had the best luck using the SD Memory Card Formatter software from the SD Association.
