I don’t know if I’ve used the right printer model in the tags, but I have got the K1 Speedy, and for some reason whenever I try to print something and I heat up the nozzle, not a single millimetre of filament comes out.
Has it worked before and stopped working, or is it the first time you have tried printing?
It did work earlier, as I fixed it however, it got tangled, so I had to cut the filament and untangle it before putting it back, but now there is some stuck inside the tube which I can’t pull out, so I tried feeding more in hoping it would follow from behind but it didn’t work.
Another thing I’d like to note is that on the symbols bit I see a picture of a wire breaking apart.
Hello @James_Cross …! 
Welcome to the Creality Forum…! 
I think the best thing would be to take the extruder out, remove the filament and check all the gears.
