I bought my first 3d printer like 3 days ago so I am very new to this but now I need help. I downloaded a few files for my self and sliced them in Cura 4.4 and they printed fine. Now my wife wants me to make her something, so she downloaded a file. I sliced it in Cura but now when I try to print her file it prints the first test line on the side of the bed fine and it prints the circle around the part fine but when it goes to print the actual part the bed drops like 1/16 of an inch I can see a huge gap between the nozzle and the bed and of course the print fails. Any ideas? Im using an ender 5 with PLA . Thanks
