Hello, I have a problem with the Ender 3 v2 3D printer /print only PLA, standard set + second z axis and bl touch/ - the problem is displayed as a printer error (squeaks) when the hotend heats up to 210 degrees. The printer needs to be reset. Interestingly, the print is relatively stable up to 210 degrees. If I manually increase the cooling to half the nominal value, the temperature often returns to normal. Most often, however, around 210 degrees, the temperature suddenly fluctuates down by 3-4 degrees, it starts beeping and shows a message about the need to reset.
