Thanks for all your ideas! I really appreciate your sage assistance. I took a bit of a breather some distance and space lets me tackle it with clear thoughts.
I ordered a BL touch and parts to make that work. (connectors mostly). I am still considering a bed replacement as that appears to be the root of the problem.
I checked the filament, The prusament is spot on at all places. I am sure there are variations but my callipers are not able to measure it. The others vary a bit here and there but 0.02 or 3 is not going to be much of an issue.
I have also ordered a replacement filament sensor.
Artillery support FINALLY replied from 3 weeks ago. I don’t expect any help there really.
