3d Printing is the Future: this time I couldn't print because the micro SD card in the printer got corrupted.
@mifune i learned to get actually good SD cards like that... and backup them :(

@whitequark I learned that from raspberry pi's and their tendency to destroy cheap SD cards.

This one came with the printer and I didn't think about it until the software said it couldn't upload the file, because the storage was read only.
