Ender 3 v2 as well, using Cura. I have followed countless tutorials about getting my Z dialed in or this or that but it never prints consistently enough for me to just leave it be. Especially now, constant hot end jams from what I suspect to either be a dying nozzle cooling fan allowing heat creep, or my bowden tube is messed up after I trimmed it. You gotta be a miracle worker to get a 100% straight cut on these!
