3D printer Marlin configuration?

That’s because you didn’t teach him the cooling and heating behavior, and on top do not print with a silicone socket. Your component cooling cools, especially if you don’t have a silicone socket, your nozzle also cools off extremely. This must be compensated. The FW recognizes this as an unplausible large heating requirement, because it could also be that something about the Thermistor cabling is going to happen or something. And then that thing would eventually come up in flames… Therefore, when the FW driver thought of something, my first printer was a “brandhot” part 2013… in this respect, a control logic is programmed in pure form, which monitors the heating requirement. If you were to print without a component fan, the problem would be “disappeared”. Also with silicone socks. Your FW must first be “angelized” by means of PID (Gcode M303), how quickly your hotend heats up and how slow or inertia it reacts, on the one hand, to enable the rapid reaching of the temperature and on the other hand to avoid the so-called overshoot. Furthermore, it learns something about how the hot end is in operation (heat demand for maintenance). It is therefore also recommended that realistic scenarios be made (temperature and component fan, as is the case in most cases). Also gives videos. Have a good one on the subject here link…!
