cooling fans object

[dadoblu_2000]

I'm using a dual extruder printer, but I'm having a problem managing the fans that cool the part, I print two materials, on the primary extruder I use ABS while on the secondary extruder I use PLA, I set the ventilation of the part on the extruder with ABS at 15% while I set the cooling of the part to 90% when I print PLA, the cooling always remains at 90% and does not change when the extruder is changed, where am I going wrong?

Bonjour,

Have you assigned the right fan number for your extruders ?
For exemple : Fan number "T0" for left nozzle , fan number "T1" for right nozzle .
