Alright. Thank you. I will give that a whirl.
Currently in front 1/3rd of a 72hr print

@droftarts
output from M39:
SD card in slot 0: capacity 7.95GB, partition size 2.14GB, free space 1.72GB, speed 22.50MBytes/sec, cluster size 4kB

@droftarts why was this marked as solved? I have not gotten a chance to get back to the printer and run M39
