Creality CR10 s pro First layer bed test - A beginners guide to a better first layer

This a first layer test on my Creality CR10 s pro 3d printer. This is a beginners guide to improve print quality. Many newcomers to the 3d printing world do not know what a good first layer is. This is the leading if not the #1 rookie mistake that leads to failed prints. Some parts of this video gets boring because parts of it is in real time to demonstrate printer bed adhesion and this is the "real 3d printing world". Very slow prints. So I will leave a timeline below so many of the viewers won't have to suffer and get to summary bits. This works on many 3d printers not only the cr10s pro. Thanks
