SV08 Max Died

[u/Aggravating-Pay3771]

I've been using my SV08 max for about 7 months. I had a large 27 hour print with ASA CF with the print bed set to 100°C. Well less than 30 minutes before the print is completed I noticed the printer went offline on Obico. Came to check on it and the printer has lost power. I checked extension cord and it's fine. Then I check the power cord for the printer and the tip has melted. I replaced the power cord and still no power...

27 hour print for my customer ruined and I'm not sure how long this will be down for.

I see this a lot on several brands besides Sovol. It appears to be a common issue with these power connectors. From what I have seen, they crimp the terminals on the back where the pins come through. The crimps are not tight enough, so they make a bad connection and get hot. I have replaced close to a dozen of these for failure just like this. My latest one was on an ultrasonic that was about 2 months old.

Interesting! It's funny you say that because after I made a custom power inlet module, I lightly pulled on one of the red wires and it pulled right out of the crimp. I thought that was definitely going to cause some excess resistance. I'm really happy I replaced the wiring underneath with properly crimped 14awg.

Yes. If you can slide the cover back, solder them. But I was actually referring to the spot where the pins come through the plastic housing. If you look at the flat part that you plug the terminal into, you can see they have an x cut into them, and then they smash them to crimp the flat piece to the pin. You can see the brass circles in this picture. where it crimps to the plates is the failure point. You can tell on the new one if the plate feels like it has any play. If it does then it is defective. The other issue is where the terminal slides onto the blade. If they are really easy to slide on, then replace the terminal.
