the list of things done:
tested/swapped out heater cartridges (new cartridge performed same as old cartridge so swapped back)
tested output of HE0, started @ 12v until hit target temp of 230 then dropped to 219 back up to 222 then temp
and voltage dropped until printer halted but HE0 led remained lit as if power was still being applied.
changed heater cartridge to HE1 and the heater faults have stopped
PID tuned again
printer failed with no error as stated in my 1st post, all motors stopped…at about the same spot as the previous failures ¯\_(ツ)_/¯
