[quote=“VEL417”]Sorry to read that you experience problems.
We do not think that there was a dead-short, otherwise the power supply would have gone into protection.
Most likely something has gone wrong with the cartridge which caused its resistance to drop dramatically, which resulted in a large current flow.
Judging by the pictures this current has flown for quite a while, since the connectors have melted too.
It is good practice to keep an eye on the printer at all times and to put it in an environment that is not likely to catch fire should something overhead. Some people put a smoke detector in the vicinity of their 3D printer.
Anyway, we use the same heater cartridge in both the K8200 and the K8400.
A total of 18000 units are now on the market and this is the first time that such a problem is reported.
Therefore, we must conclude that the chance for this to happen is very small.
Because it is very rare, we’d be happy to replace the affected parts.
Please drop us a mail (supportatvellemandotbe) and let us know your address and the order code of the parts you need to replace (you can find the exact order codes in the manual when you hover the pointer over the item).[/quote]
Merci pour votre retour, j’ai regardé et je n’ai pas trouvé de protection autre que dans l’alimentation.
Si je ne me trompe pas, elle fait 150W donc le fusible doit être de 10A.
C’est pour cette raison que je vais mettre deux fusibles de 2A (un par tête).
et je vais investir dans un détecteur de fumé.
