I bought my Sunlu T3 as part of a promo where I needed to contact them directly. Super helpful people TBH, but below is what their recommendation for a slicer profile.
"For the slicer profile, this is what a friend tell me : What has always worked for me: I just set up new printers with a generic "Creality Ender 3" profile. I check to make sure the bed size is the same (example 220x220x250) and that is fine 99% of the time."
