Fresh install, changing the USB Cable

Have you tried running in safe mode?


Did running in safe mode solve the problem?

1 hour print ran fine without issues

Additional information about your setup

OctoPrint Version 1.10.1
OctoPi Build 2024.05.14.100113 with "webcamd", based on OctoPi 1.0.0, running on Raspberry Pi 3 Model B Plus Rev 1.4
Wifi connection on RPi

What printer do you use? - I had similar issues with my Ender 3 V2 and it was in fact the USB-socket from the printer, which was relatively loose. I had to carefully bend the shielding from the socket to that it makes a good and strong connection without the plug wobbling in the socket.

I assume that you have covered the 5V on the USB plug so that the Raspi- and printer 5V are separated.
