Thanks so much for the info, I have tried the pause at height also with no luck, my printer just doesn't seem to like the M600 code. I did reach out to Elegoo and followed their instructions again without success. I'm too scared to tell the wife I need a different printer and to be fair the Elegoo has worked flawlessly aside from this issue. At present I am guesstimating where to pause it manually to do the filament change with varying degrees of success. Perhaps a different slicer or the more terrifying update of the firmware is required?!?!?!
