Hey guys, so recentyl while prinitng with my robo3d ive had prints that after the first layer the temperature drops up to 10 degrees and its seems to cause my layers to not adhere very well, i have ae3d hotedn dual fans and an lcd display, i was wondering if all these mods are the cause of the temp drop, let me know what you think. Thanks for any help

the extruder fan is essential to avoid hot end jams but the parts cooling fan if not properly placed or blowing too much or too fast will cool down the nozzle too much reduce it to 0% to 50% till your happy to experiment cover the parts fan intake with a piece of paper and see the temp rise. Also printing in a drafty cold garage or basement in alaska will be different than Arizona try a cardboard box over the printer keyword try not a permanent advisable replacement to doors walls windows the default 100% ok for bridges also look at different 3d printed fan attachments and orientations to cool the part not the nozzle -
Ok ill give that a try, but i did just notice that after a certain duration of the print the temperature goes back to how it should.Comment

never mind that it is doing it through the whole duration of the print i am printing a new fan duct now and hopefully that will do the trickComment

ok so i removed the fans altogether and the temp stayed right i was wondering if there were any recommened fan ducts that would not give me the same issue. Thanks for the helpComment

if you look on thingiverse for Dyze it will give you an idea sort of a shroud the nozzle fits thru with outlets than blow straight down on the bed not at the nozzle, my MK8 will cool down 5 to 10 degrees depending on its speed but anticipating that set the start temp 5 deg hotter for all layers or reduce fan to 50% or lessComment
