In this video we will take a look at my findings regarding first layer adhesion issues and the auto bed level 203 (Probing Failed) error on the Creality CR-10 Smart and CR-6 3D printers.

I came across this issue when setting up my CR-10 smart and through my online searching have noticed that many people are having difficulties with this printer. First layer adhesion is problematic for many and some, such as myself, even get the probing error whereby the printer cannot successfully probe the print surface.

To compound the problem, the user interface for setting the z compensation height is not intuitive or user friendly and it is causing more confusion for users.

I will show you how I fixed my 203 error and then went on to successfully probe the bed and use the auto bed leveling feature to lay down some nice prints.

I would also recommend using glue stick... the Creality glass bed isn't that great with adhesion when bare, even when using PLA. A bit of glue stick went a long way in adhesion promotion in my case as well.

For those of you reading this, I would also like to CONFIRM that the printer does, in fact, appear to be making Z height adjustments across the first layer and all subsequent layers on prints when using the auto bed leveling feature. There was speculation from @TeachingTech that no mesh file is loaded in the gcode and therefore the printer is actually not employing the auto leveling feature to compensate for variations in the print surface. However, I have performed some very large first layer prints spanning a great surface area on the bed and the z couplers are obviously moving during the printing of the first layer, so something is happening here. How it works and where the mesh is being loaded, etc. is not something I have investigated but at least it appears to be working!

Here is some great technical information regarding the Creality strain gauge system in the print head and other troubleshooting techniques:
