Temperature E0 drops to 0 after few hours of printing Anycubic i3 Mega

[Akashigiri 0]

Hello,

 

after a few hours of printing the targeted temperature E0 drops from 200°C to 0 AND the bed temperature drops to 0 too (with an error message). After 30 hours of printing my print failed and I couldn't resume the printing again. My fans are working fine. What could be the cause?

 

UPDATE: New power supply arrived. I installed it (+ new silent fan, the original is very very loud) and i started a new print. 30 min printing and looks fine. Will update again the next day!

 

UPDATE 2: I think the new power supply did the trick. After a 33 hours print everything was printed fine without interruptions of any kind (like hotend or heat bed temp drop). I guess there was either some high peak voltages sometimes that killed my original power supply. Now I'm using a multi socket with an inbuild overvoltage protection.

Sounds like a hardware failure or problem.
But you will probably get more help in an appropriate Anycubic forum.

Someone uploaded the same problem described here

 

power supply was defect/dead. I ordered a new PS now and hope it will solve this problem.

Yeah, that could be the power supply, too.
Please give us some feedback if it fixed your problem.

New PS should arrive tomorrow. Will install it and after 1 or 2 days of printing i will give feedback if it did the trick!
