Provided USB stick issues?

Hi all,

yesterday I encountered the Watchdog Reset issue with my mini. I think it was mainly due to the Prusa USB stick. It was just really hot (felt like hot tap-water).

I just reset the Mini, used another USB stick, and now 15h later no issues (it's a 29h print).

I had already noticed that the Prusa USB stick is really slow. The same files transfer 5 times faster using my other (USB 2.0) sticks.
Also unmounting the USB drive takes ages, and sometimes I have to force unmount it, in order to get it unmounted in OSX.

I was just wondering, am I the only with this issues (slow read/write, slow unmounting, stick getting hot)?

 

ETA: just found out I could get the complete errorlog of the Watchdog reset, forgot to do that. Will see if it is still possible

The original Prusa USB stick is well known for having issues.

good to know. I searched but could only find an issue about the USB on the i3, not with the stick itself 🙂

What a coincidence. I got my first watchdog reset yesterday since receiving my Mini in February. I had noticed the USB stick getting progressively hotter over time. Tried the print again and got another reset. Tried a different stick and had no problem.

Have you updated to the latest firmware (4.1.0)? There have been a number of fixed for USB / watchdog issues.

hi Gordon, I'm running the latest firmware (4.1.0)

Since I'm still printing I can't check if there's info in the system logs as to what went wrong

I set mind aside and I am using my own USB. The USB that comes with the printer is defective. I encountered this issue too in the middle of the 2nd print.

My prusa usb still work fine, it hot when it is printing. Slow speed is acceptable for me due to printer doesn't need high speed usb. It survive from my washing machine too :-).

If the Prusa USB is hot, I highly recommend you stop using it before it ruins a print.
