Behavior

Context: I am using "heavily modified" printers with 2 extruders. Sometimes I print a part with extruder #2, because it is 0.8 nozzle with X color PLA. Extruder #1 is PETG with 0.4 nozzle, and not suitable for my part. Description of the problem: In the attached 3mf file I am using in extruder # 1 a filament named "No filament". So my startup script tests the value of the parameter of each extruder (first_layer_temperature [x]) and purges only the nozzle used. So I avoid purging and heating the inactive nozzle. In the attached file, extruder #2 is black ICE PLA with a 0.4 nozzle and extruder 1 is "No filament" (ivory PLA in reality) and a 0.8 nozzle. So I can print my part with nozzle #2 in black PLA without any problem. Except that the cooling parameters only take into account those of extruder #1. Indeed, I voluntarily set the filament of extruder #2 with a fan speed of 0 in layer #1 (the first layer) to 100 % in layer #4. But in the gcode the fan goes to 100% at the start of layer #2. In summary, the cooling parameters for extruder #2 do not seem to be taken into account.

Is this a new feature request?

Project File (.3MF) where problem occurs

Upload a PrusaSlicer Project File (.3MF) (Plater -> Export plate as 3MF for Slic3r PE 1.41.2 and older, File -> Save / Save Project for PrusaSlicer, Slic3r PE 1.42.0-alpha and newer) PS2.3.0-rc2_Pbl.zip

Images (PNG, GIF, JPEG), PDFs or text files could be drag & dropped to the issue directly, while all other files need to be zipped first (.zip, .gz)

Hi, This is a long time known issue. PS doesn't handle properly setups with multiple extruder yet. Related to https://github.com/prusa3d/PrusaSlicer/issues/3704.
