Why do my prints always start bad?

[JennahS 0]

I made two prints of the same thing as a test. I found another simple print that i added to my sd card and got my printer to do its thing. But when it prints it starts off good then will randomly get stuck or something and the whole print comes off the bed and sticks to the nozzle. I adjusted the leveling so many times. But it is still happening. Any ideas on what i could be doing wrong? I have a easy threed k1 mini and am just starting out. So there is a lot i am probably doing wrong.

When a print comes loose it is most of time a wrong leveling. Also if you did the leveling already many times, it does not mean you did it correctly. I would try to level a bit closer that the first layer is squished into the bed a bit more. 

 

Another reason could be that you need to clean your print bed or apply some glue stick to increase the adhesion. I don't know your printer and don't know if it uses a glass bed or something else, but that's the second reason why a print gets loose.
