Describe your issue:
I’ve been having some random crashes and I can’t figure out what the issue is, other than blaming on the Pi, at start from months ago, if I have anything mroe than 2 USB connected, I would get this crash happening very often, I then removed all USB devices, left only web came and octopus pro v1.1 h723 board, running can bridge from it, I don’t have toolhead board, just cartographer, I did have an ebb36 but it slowly failed one thing after another on the board so I removed it, as ity went to the point it was not giving enough current to the extruder, but thats another issue to deal with, when I have this figured out, I have webcam 5v wired to 5v 30a PSU, as well as the pi itself, and the LEDs, I don’t get undervolt on the pi as it is getting plenty enough current.
after I made those changes, the problem though to have went away but it didn’t. couple of days ago it was sitting with just heatbed on for heatsoak before I start a print with ABS, and it crashed twice, I checked all the wiring, everything seems to be fine, I even wiggled the wires after restart, nothing made ti crash, and it has been printing fine, and suddenly it did the exact same thing again, there no bytes_invalid, in the log but there are bytes_retransmit, I am running 32bit pi, as I was having this issue even more with 64bit. I looked at the log but I cannot figure out what the problem is, other than the pi being 7years old, and there always has been issue with USB ports, even though none of them are suplying power to anything I plug in to the pi, I always have 5v cut and power from PSU. if someone could give me some insight from the log would be great.
thanks
