Greg, thanks for the reply. I will try your suggestion this morning. My description wasn't adequate. Last night I remembered I also have Prusa slicer on my computer so I sliced the same object wih it and the printing location was normal in the center of the bed. I also reloaded Cura 4.4.o and now have the same problem when slicing with 4.6.
When using 4.6 the printer lays down a strip of filament very near the left edge of the bed and then comes back to the left front corner and start printing my object. The Z position appears to be normal but the object is partially printed on the corner of the bed and partly in the air to the left of the bed.

I sent the whole file to a friend who has the same p;rinter and is using 4.6 and I will hear from him this morning.

A picture is worth a thousand words. Do you mean it's angled off the bed somehow? Air printing in the left front?
If the bed is level I don't understand how it could do that. I installed 4.6 and now 4.6.1 and there haven't been any issues with the 3 Pro.
Create a gcode file of any model using - Cura 4.6, .2 layer height, with a skirt for bed adhesion. Open the file in Notepad and scroll down until you find a Z value. It should look something like this:
G1 F300 Z0.4
G0 F4500 X75.844 Y52.594 Z0.4
;TYPE:SKIRT
G1 F300 Z0.2 ;This line is the "drop down" to the working height.
G1 F1500 E0
G1 F3000 X76.798 Y52.659 E0.03254
I had a situation where it appeared that my bed had warped. It turned out that I had been adjusting the left front and right rear screws excessively and the bed had become bowed from the uneven pressure of the leveling screws. I took the glass off the bed and using a small block under the nozzle (about 5mm high), I leveled the bed with no build surface on it. That fixed it.
