Beginner Help

[cherrykaleb]

I am trying to get a Creality CR-10 Max to work for a friend. I know very little about 3D printers. The problem is the control not reading my SD card. I have tried all the different types of files that the manual says are supported and have still never seen any files on any of the 5 pages of the print screen. From reading some other posts I think it might be the micro SD card I'm using. I just bought a cheap 128gb SanDisk from Walmart. I've seen some posts saying the SD card size needs to be 16gb or smaller or that it could be that the SanDisk is too old/cheap. Any insight would be appreciated.

Are you copying .stl files to the SD? If so, you will never see them.
You use a slicer program such as Cura to set your print params and slice it, creating a .gcode file.
That's the file you put on the SD.

make sure you've reformatted the card to fat32.
Most modern sdcards come preformatted with ex-fat.
A lot of systems can't see exfat.

Sandisk are the best you can get - so check the formatting.
And creality do use dirt cheap electronics, so you might need a smaller card as well

And i apologise in advance but this did made me laugh :

But presumably you know more than your friend :-)
And had the sense to ask :-)
