Toolboard Shutdown
Printer V-Core 3 (Upgrade to 3.1)
Board Octopus 1.1
Toolboard EBB42
I am currently printing many large parts, the first 8 parts worked without any problems, then the error occurred just before the end of the print
first thought of a coincidence, then restarted the print, it worked 2 more too
then the error came again, checked everything and replaced the USB-C cable to be on the safe side
The power supply is tight and fixed
3 prints then worked without problems now the error is back
I suspect that the usb cable loses the connection due to the movement of the print head, although this is sufficiently fixed
maybe someone else has an idea

I chose the wrong area, maybe an admin would be so kind as to move the post to fix my printer
Zip tie the hell out of all the wiring even more and also try another usb cable, it definately looks like lose connection.

i use higher quality usb cables and the cable ties are very tight
maybe the holder has too much play with the minion, it works without any problems, however, the movements are not as far-reaching as with the v-core
It could very well be, I've heard about USB C holders not soldered well on some Chinese boards. How is your resonance, it could help to shake your wiring loose.

smaller parts printing without any problem when the distances are shorter but yes, bad solder joints are also an option
resonances are okay i think

I wonder if your umbilical cord may be too tight and putting strain on the wiring on the longer runs.

It seems it was really just the usb-c connector that lost contact with the board when the print head moves backwards there is some pressure on the cable. I have now designed a holder for the cable and it has worked flawlessly so far
I am glad you found the problem.
