I have a problem with my ender 3 v3 plus and I wanted to know if other people have already encountered this problem and would have advice. When I was printing, I smelled a strong smell of melted plastic. I thought it must come from my carbon reinforced spool being new. Then at one point my printer stops and displays the error code CB2565. The problem would come from the heating of the plate, I search on the creality wiki, find the explanation and the solution. I check the connectors. That’s when I realize just before the connections to the plate, melted cables and completely cut in two. I had thought of soldering them, but they will be too short and what does not reassure me is that they do not touch the plate. So they would have melted because of a surge? I was thinking of changing them, but in your opinion would it not be better to also change the power supply in addition to the cables?
Small clarification, the machine is a few months old
the sheath behind the red cable is melted too
and the cable protection has suffered a little but it’s less annoying than the rest.
What is the red and black cable for? For heating or moving the platter?
A tricky one … I can only guess at this point and say,“heat bed wire” is the broken one.
Another guess would be that the cable was severed but not fully through and as such the current for the bed heater, made the strands of wire get hot enough to melt things and eventually give up.
Or… did something slice at the cable and in doing so shorted the power to the heater and go from there…
I am wondering why the cable became cut in the first place.
I had looked when I had installed my printer in my cabinet, that nothing was blocking the cable of the tray and that it was not crushed against one side. I looked again but I still do not understand how it managed to cut itself. I was thinking of changing the cable but I see that it is welded under the plate. Is it better to change it completely or to weld the cut part?
I personally would take it apart and fix it, but that is because as a repair technician for much of my life, I am just that way inclined.
If you feel in any way unsure of doing it, by all means replace the whole thing.
Thank you for reply. I managed to change the cables but I find myself with a second problem. Another cable is damaged and connected to a jst connector SH series of 15 connectors on a row. Only one cable is at the limit of this cut. I can’t find this cable, so I thought of finding the female jst connector and crimping the cables directly into it. To be sure, it is indeed a Female connector, 15 contacts 1 row, 1mm pitch, Straight, SH series? It is linked to the Hotend Adapter Plate card
If that that wire with the badly crushed insulation is actually open, it should be easy enough to cut that wire & solder in a tiny splice, & cover it with a small piece of heat shrink.
Hopefully that wire did not get shorted to ground or you may be looking at another challenge.
Good luck
From what it looks like, the actual wire strands are intact.
I personally would simply paint a bit of fingernail polish over the bare strands to insulate it.
