here my settings and my materials
t-shirt brand - cotton heritage 4.5oz ringspun . very nice and sweet for DTG
firebird pretrement. about 2oz on 30*40 platen (i dilute the pretreatment with watter using 3parts of pretreatment and 1 part of water) i do this not to get more prints. i dilute it cause water helps to make a robust application.
and duppont artistr ink
so
spray about 2oz of pretratment,
for curing i use 305F and go for 10secs the let it breath a couple seconds and go another 10. 0 presure
after print, i do 0-1 presure. 60secs+60secs + 60secs if a lot of white underbase. so total 180 if not to much white underbase just 60+60
cure is ready when no steam cames out when you lift press.
hope can help you
