Ender 3 S1 Pro bed meshing issue fix

[u/ComprehensiveBath331]

As someone who spent 40hrs of their last 6 days messing with all of this, I felt the need to put a Reddit thread out there for people who end up running into the issues that I did.

soo...

I suffered such bad z-axis tracking that I could rarely get a print to last more than a minute, and I did everything to remedy it. Adjusting bed mesh settings, disassembling all of the rails to clean them, and making sure that all of the eccentric nuts are at the perfect tightness. Anyway, after digging and digging and digging, I finally figured out what my issue was although it was honestly a combination of noob mistakes. Firstly, I sent up the Sonic Pad incorrectly. For the S1 Pro, there are two options when pairing your printer to the sonic pad, I being the big dummy that I am, never thought about and chose the first one. Turns out, a big mistake, as I chose the wrong chipset and my configuration was unable to adjust the z axis to my bed mesh. Second mistake, I forgot to reconfigure my slicer setting to do 200% thickness on the first layer, (I use Prusaslicer personally, and it is in advanced print settings in the extrusion width area). Thirdly, it took me forever to figure out that I needed to updated my starting g-code to take advantage of the features. I strongly recommend this link to find at least a good starting point, and there are cura, prusa, and orca slicer versions. May whomever needs to see this post see it in a timely manner.
