I have spent parts of the last 2 days trying to finish calibrating a hardened stainless steel .60mm nozzle with Sunlu PLA+ 2.0 filament.

I have been trying to print a test cube and I couldn't get the first layer to stick period. I washed plates, I swapped plates, I removed the nozzle and reinstalled it.

I swapped different filament brands, and they all printed flawlessly. Try that Sunlu white PLA and instant failure again. I was about ready to admit defeat and dry my first spool of PLA ever because I could think of nothing else to do.

But I took one last look at my settings for this filament. And I finally noticed my flow ratio was set at .096 rather than .96. I didn't even know the slicer would allow a number that small.

Once again the error was found to be located between the chair and the screen.........
