Thanks for the quick reply.
I have not tried a cura connect reset yet, didn't think that would affect the bed level.
When I do a manual level I follow the onscreen instructions. I do not have a z offset plug in.
If I try and do a manual bed level, the print is a good 4 to 5 mm off the bed and that's right after I did a new level.
When I do an auto bed level I need to adjust all the screws by about a quarter turn to pull the bed away. If I don't, the nozzle is so close that nothing at all comes out of the nozzle, but the prime blob is working so I know the extruder works.
I print with a skirt, I rarely use a brim unless I have to for a large print. I don't tend to have issues with adhesion.
I don't really know what I'm looking at when I look at the raw GCODE but here is the gcode for one of the most recent prints that I had to manually adjust the bed for.

I have checked all the wires in the back of the print head and the red wire for the bed level is working. When I run a diagnostic on the bed level sensor it says it's working good.

When you do the manual leveling, do you turn the knob on the front of the printer (not one of the 3 leveling screws) when you level the rear spot? And do you turn the front leveling screws for the front two locations? By the way, unless you change the 3 screws a *lot* you can just skip over the whole "1mm" steps.
Are you sure you don't have a Z offset plugin? Can you post the first chunk of gcode? About 50 lines - up until where it sets Z for the bottom layer (typically 0.27mm) and then starts printing the skirt or brim.
