I have an Azteeg V2 (should be the same as the V3) and cannot get this microsd to read the files. Its formatted to FAT32 (16 KB) [I didn’t see an option for FAT16], meets the 4 gigs or less requirement, and I’m able to upload files. Literally nothing shows up after the file uploads in mounted card within RepHost. Help?
What host are you using? I could never get it to read in repetier… But via the LCD and octo print it works great.
I had the same problem on my printrboard. Make sure the filename is 8 characters or less, no spaces and uses the .g extension. i.e. “filename.g”
oh not .gcode? interesting
@Custom_Creations Dude, that software worked. Thanks you!
I’ve seen 16GB cards work. They have to be formatted FAT16, and apparently only the first gigabyte will be readable (haven’t run into that barrier on any of my cards yet). The card does have to support SPI mode, which was required in the SDSC spec, but is optional in the SDHC spec, and is less likely to be available on larger cards (it’s also not listed in any of the product descriptions, so it’s kind of a gamble).
Repetier Host’s SD functionality is horribly broken, at least when working with Marlin. I assume it works better with Repetier firmware. Pronterface’s SD functionality works better, but I do most of my SD printing from auto0.g.
The FAT16 filesystem requires file names to be natively 8.3 (1-8 character name, followed by a 1-3 character extension), but modern operating systems (at least I know it works on Macs) have a way of faking it. If you put a file called “something.gcode” on the SD card, it will quietly be replaced with “somet~1.gco” (with the 1 being incremented if that name is not available), and the real name will be stored in some hidden location so that the it can show you the long name instead. Marlin’s LCD support can also show you the long name, though I think the host-based file selection still only shows the 8.3 names.
