The printer freezes and cannot be turned off and on again, it restarts, but stops after a few seconds
Some more information would help getting a possible solution.
Also, is the mains set for the country you are in ?
Yes, the network is correct, I bought it in November, and until the other day it had never given me any problems.
I noticed that the printer turns off when it starts heating the plate
Possibly the Solid State Relay has developed a fault or the Power Supply has somehow lost power. Have you added anything electrical to the printer recently to draw more power ?
no I didn’t add anything
