Stopped, surface cleaned and print restarted 2x; same failure each time
Fan test result: OK
Last try, selected resume then changed fan speed was 15, changed to 'off'; speed 150%.
Same fail with fan speed error
Retried resume with Tune/Print Fan set to 'off', speed 150% ; success, no error!
Tune changed speed to 200% briefly to check while printing, no failure.
Still printing, changed Speed back to 150% speed; fan had automatically changed to 30 (g-code caused?) but still printing; now at 1.2 level. Left Fan at 30 and crossed fingers.
