FL sent me the sane instructions. The frame CPR didn’t work for me because I still got the error after I attempted it a few times. My grounding screws were torqued down from the factory tightly as well but I backed the 2 screws out and re torqued them and have never seen the error come back. I’ve been printing for about 2weeks every day since the grounding screw adjustment and haven’t had an issue since.
