ASA Fan setting

Bambu Lab H2 Series
1

i have several x1cs, print asa daily very few problems. I have a 2 large pieces 245x31x136mm

i have 2 this size but are slightly different. 1 of them, the black one, prints fine on x1c, the gray one gets a crack in it after printing on the X1c, not every time. disregard the red X crack. i threw it on the floor to see if the other crack would break more and it didnt.

the crack after printing is the red arrow. i have had this several times.

I have been printing with a .4mm nozzle. layer height is .24

260 noz temp

10 wall loops, 15% gyroid

I don’t understand the fan settings, would you change this?

this is for the H2S I unchecked the “Keep fan always on”

this is a 20 hour print

i have quality issuse with the H2S on a lot of other prints, prints not printing smooth on lower layers.

but my main question is fans settings on ASA

Thanks!

I keep all fans off except for overhangs

Thanks!, when checking my filament cooling settings I noticed that some had fans on, so that seemed to fix my problem. I have been printing those large parts with no problem now.

Where abouts was that setting you found? As it looks like on your screenshot above they are all off. Do you not get sagging overhangs with them all off? Or keep them on for overhangs?

that is the default setting in the h2s, i only changed the fan setting to unchecked fan always on.
