Printer stuck going to a non-existent "Projects" folder
I have a Prusa Mini that has worked fine as long as I've had it. Recently, it stopped seeing GCode files on my thumb drive. Admittedly, I hadn't used the printer in a while, and I'm not sure where to begin on troubleshooting.
- Thumbdrive was used to do a firmware update on a CNC Router table; since then, I deleted all partitions and re-formatted as FAT32
- Prusa Slicer software probably got updated
- Prusa Mini firmware is at 6.1.2+7894
The printer "sees" the thumb drive in that the "No USB" icon changes to "Print." However, when I select the Print icon, it goes to an empty "Projects" folder. My thumb drive has several folders on it, and none of those are listed. I do not have a folder named "Projects" anywhere.
I have tried saving files as both binary BGCode and non-binary GCode, and nothing shows up. Also, I downloaded Sample GCode files for the Mini and loaded those onto the thumb drive as well, and nothing shows up on the Mini.
Can anyone figure out what is going on? It's like the printer is going to a folder on a hidden partition, or on the printer itself??

Do a full format using MBR ( instead if GPT) and use Fat32 for filesystem.
Or get different pendrive, this one may start to get corrupted.
Also check if other pendrive is detected, maybe your usb connection on the printer went bad?

So what happens if you click on Return? That should take you to the next level up. The printer "remembers" what directory you printed from last, which may no longer exist. Once you print from a different directory you should be back to good.

If I hit return, it brings me back to the main menu.

Also, I just created a folder on the thumb drive, named it "Projects," and placed some files inside of it. The behavior is the same on the Mini, as seen in the screenshots above. No files are shown, and hitting "Return" brings me back to the top menu.

See my GitHub and printables.com for some 3d stuff that you may like.

Thanks for your response! I found a USB adapter for my SD card, and the printer read that with no problems, so the issue is certainly with that thumb drive.
I will try formatting as you mentioned, and if that doesn't work, it'll be $5 for a new one.
Thanks!
RE: Printer stuck going to a non-existent "Projects" folder
Just wanted to say, this was exactly the problem. I had used this same thumb drive to update firmware on a piece of hardware, and the flash tool had to be bootable. This must have converted the partition table to GPT. I figured the two were related, but didn't know what to look for.
Thanks for your help! Learned something new today.
