The temperature of the print head drops during printing. I set it at 221C but while it prints it drops down to 204C then maybe back up to 210C at points meaning the filament doesn't feed properly as it's too cool.

Is this a print head problem?

Are print heads available to buy? If so is there a link I can get a spare?

Hi,
Maybe it has something to do with your room temperature. Is the room temperature too low?

Nope, normal room temp.

I bought yet another new print head and it's fine now.

Cheap Chinese shit, terrible soldering...
