Have a new Ender 3 that appeared to be working great. Until I tried to print multiple items. I need 3 objects. The first printed just fine. After it finished, I started another and it worked great. However, the third time I tried to print it, it just will not work. PLA goes everywhere, will not stick to base and just gets generally messed up. Absolutely no changes were made. just tried to print the identical object 3 times. Have photos of the mess it made.
It sounds like it has an issue printing one item. Without seeing the part, and the base (first layer) it’s hard to give any advice.
