Print stops randomly, Klipper reports shutdown
Hey guys,
My ratrig randomly stops printing and shuts down. I've no idea whats happening there.
I use an octopus V1.1 with an EBB42 V1.2.
Thanks for your help!

I also did a bit of research and testing, that lead to 3 "major" changes:
1. I desoldered the clamp mechanism of the the heater and replaced it with a silicon cable with an 30 Socket at the end of it. I did that because the clamp was really close to the fan and I wanted to avoid tight bends of the cables.
2. I replaced the self crimped atx cable with one from aliexpress with a lager diameter. ...

Check your wiring, especially check for faulty crimps and usb cable connection (hopefully you have a decent usb cable), those are usually the problem.
I have an anker powerline. The description says it's usb 3.0 and it feels pretty hefty. Do you know how the plug of the can / powerline is called?
Anker is usually good quality, but you may want to try to re-seat it. Sorry don't know the plug, but it should have been included with the toolboard. You are getting power to the board so that should not be the problem.
yepp, a) good quality usb cable (heard 3.1 somewhere) which can handle the high bitrate / canbus frequency properly and b) all involved MCU and CPU must be able to handle this (beside the other tasks) in time / without delay
For more, e.g. check

… some thoughts in addition:

No, you don't want to use CAN | RatOS
No, you don't want to use CAN.
Yeah it was included, but the crimping was not my best job, so maybe the connection is bad and it loses power sometimes? So my Idea was to buy a cable insteat of a crimping tool, to make it right.
Thanks for the links! But the only thing I see, that I've done "wrong", was using a usb 3.0 cable and not a 3.1 one. Do you have a running toolboard? Which cable do you use?
Nope no 1: … i do not have a toolboard setup because of this. still thinking about the pro and cons
Nope no 2 .. your USB3 cable may work and the root cause is another component, the combination of several things … etc. pp.
I‘m not sure if there’s anybody who can tell you „exchange this part because this is the root cause“
… at the end all involved components (hardware, software, environment) needs to be checked because there are dependencies
I once had a problem like that and fixed it. The problem was as incredible vibration from my part cooling blower fans, 2 of them. I then printed some silencers and also got a bit of cork in the middle of them. Once stuck in there the vibration went down almost to zero and it never failed again. If the vibration is big as I had, causes the usb connector to not making good contact at 100% of the time
I will defintely try that!
I get that at random times, even when printer is idling. No common cause I could find, fortunately it happens once a week or less. Annoying, but I learned to live with it.
Its all about reliabikity of the connection, cause by loose connectors, bas cables or vibrations shaking the contacta too much. I gave a lot of time and research on this topic. Another thing that might help is with needle pliers bend the usb-c connector, just a bit so the male connector enters the usb female connector just snug or tight.

3. I designed an own mount for ebb42, where I can fix the usb-c cable properly.

That seams to have solved my issue. I'm printing since around 24 hours and everything is going well so far.
Thanks for the help everyone!!
