Hello, I started making the smooth recon helmet but in the end I didnt like it as I managed to mess it up a bit. Anyway I went to print out a new one but all that comes out is a black page and you can , with some difficulty, make out the joining number in amidst the blackness but nothing else. Seeing as my printer is pretty crap, jams literally every time and also starts to randomly print bar codes on its own accord i assumed it had finally packed up but when I tried to print using a different printer i got the same results. Now only 2 days ago I printed the exact same file and it came out perfect so why would it change it now? I have re downloaded the file in case its corrupt but still it wont work. Any replys would be much appreciated and the sooner the better because I am back at college soon. Thank you and sorry for any speling/ grammar mistakes, im in a rush because my fridge has started 2 leak and i need to mop it up
