I'm new to 3D printing, I've just assembled an Ender 3 Pro, but the filament does not appear to be sticking to the bed. The PLA is heating up to 200, and the bed to 65. As I said, I'm very new to this so may have made a basic error ! Any help or ideas would be greatly appreciated.

(I've tried to post a video but I need to make 3 posts before I can apparently, so I will do later in the thread.)

Thanks
John
