Watchdog reset on every print

Hi there, 

I got my Prusa Mini today and after calibration started a few test prints. I started the prusa logo as recommended and half way in the print the screen showed "Watchdog reset" - nothing else. After trying again, I was able to print the logo adn started a 1:30 test print. Unfortunately that print was interrupted by Watchdog reset after about 50% of the print.

That's pretty annoying... any ideas how I can fix that?

I was in touch with customer support and they told me to preheat to PLA temp and then wiggle the cables to check if the error occurs (due to loose/faulty cables). Done that, no error. I then started a print (the screw, from the usb stick I got) and it was printing perfectly for the first hour or so. Then again: watchdog reset.

This is very frustrating, I really hope for a quick fix. 

 

thx

Sven

Me too. I tried reslicing, wiggling cables, reflashing FW, recalibration. Can't get through a print, no matter what it is.

Are you printing from the supplied usb stick? I was having the same issue and saw that the usb was really warm to touch. After trying one of my own usb sticks the error did not return.

I just finished putting my printer together and I am getting the same problem with every test print I have tried

After trying many things, it was that POS thumb drive Prusa sent with the mini. Any other thumb drive works fine, I don't see the issue.

Got my mini today and had the same issue, it turn out to also be the POS thumb drive. Thing was pretty hot to the touch.

I must be the only one who's not having trouble with the Prusa provided USB Stick.

My original supplied USB stick got very hot after seconds and was defective after 2 weeks of moderate use. I replaced the stick with a noname product, which still works today. I think that this problem is very widespread. Apparently there was once a bad batch delivered.

I'm going to +1 this, the thumb drive that came with my Mini died pretty quickly, I use a SanDisk now to update the firmware and OctoPrint to send prints to the printer.

Had the same problem on my Mini, but I use USB extension cord so my thumb drive is not directly plugged in and never got hot.

I ended up replacing hotbed thermistor and since I had a single error in over two hundred hours of printing.
