Hello I have recently bought an anet a 8 diy kit . I assembled it and I printed a test file . The other day I went ahead to print. it started printing alright but unfortunately it got unstuck from the heat bed so I unplagued it because I don't know if there is any other way to stop the print . Then I plagued it in I put some some hair spray because I have heard it helps the print stick in the heat bed . So I loaded the file and it didn't start extruding . I took apart the extruder I cleaned well the nozzle when I went ahead to assemble it unfortunately the screw above the nozzle broke I managed to do something with some nuts and I fixed (first picture below ).It printed some thinges quite nicely but after some prints it wouldnt extrude again . So I want to order some screws to fix it and a couple of nozzles but I don't know if it is going to help . Any ideas ? Also I want to order an e3d v6 hot end but if any of you have done this upgrade do you know what else do I need to buy and if I can mount to that hot end an auto bed leveling sensor and if yes what model? Please help me with my problem :)!
