Auto Leveling Problem
I'm having problems getting my printer to auto level correctly. It has a probe auto level feature that seems to run just fine but no matter how many times I use it, my first layer is still messed up. After auto leveling and adjusting my Z offset it still prints uneven. From the first layer it appears that the print head is closer to the bed surface on one side vs the other. Isn't the auto leveling supposed to compensate in the Z during for the uneven surface?A couple strange things I noticed from the outputs below:1: My filament is set (default) to 3.00mm in the firmware and I'm printing 1.75mm with no extrusion problems from what I can tell. Once I change it to 1.75 it does not extrude at all once it begins printing. 2: After M420 it says that bed leveling and fade height are off but it appears to run through the bed leveling process with no issues.
What mechanical problem could be causing this? Is it worth considering a firmware upgrade/how hard is that to do?

When first learning 3D Printing though was using auto leveling but later found out I was not.
In order to use the auto leveling on my 1st 3D Printer I had to add M420 to the end of my slicer G-Code. Then was printing with the auto leveling on.
I would select the auto bed leveling form LCD
I would save the Data using Store Settings or M500
The in the Startup G-Code world restore Bed Leveling Data M420 S1 see My Cura Startup G-Code below

Wanted to make a foot Note Here.
When I upgraded to Marlin 2 some time Ago had to forgo the use of M503 as not using it saved me enough memory to enable me to use the Marlin 2 versions.
New to 3d printing looking for...
