I might have the answer to this myself.
I took an old printer out of storage and got bed leveling to work on the first try. I think I have a mechanical problem. I have changed to a e3d hemera extruder and made some other changes that I think are to heavy for my X-axis rails to handle. I can make the carriage flex with just moving the wires going to it. I will get some new beefier hardware and try again.
