I have a K1 Max that is only 3 months old. I had to change the heat block and hot end because I ended up with a blob of melted filament. Now I can not get it to extrude properly. It will go to extrude the filament and it will only extrude 1 time. I try to extrude it again and it will not extrude, I have to manually push it down. I have broke it completely down 2 times and still can not get it to extrude right. I have not been able to print on it for a month and I am not sure what exactly else to do. PLEASE HELP
Hello @Carrie_Wingo …! 
Welcome to the Creality Forum…! 
You might already know this but just making sure to cover all the bases make sure the lever on the top of the extruder is pushed to the locked position. (left)
Yes the lever is in lock position. I ordered a new heat block from Creality today so hopefully one from Creality itself will fix it. But I will break it down again tomorrow night and look at ever again to if I missed anything
possible there is melted filament inside the heaterthroat so you need to clean the heaterthroat with a heated iron bar of the heaterthroat diameter. watch out for burns.
first take off the extruder and the nozzle.
