It concerns the part cooling fan, in the filament settings.
The Layer time of the Max fan speed threshold should be 125 seconds for the first 200 layers. From layer 201 onwards, I’d like to reset to the default Layer time value of 8 seconds.
The reason to increase layer time for layers 1-200 is that the specific filament needs extra time to dry.
I’m looking for the right G-code settings. For example, if I could add custom G-code on layer 201, bringing back Layer time of the Max fan speed threshold to the default value of 8 seconds, this issue would be solved.
I’ve already experimented with Dwell (G4) and Fan Speed (M106), without any luck.
Layer time is used as a rule in the slicer. As such, it is responsible for local speed calculations but does not translate to the gcode itself.
You’ll have to change speed settings above the desired layer with a height or volume modifier.
You’ve pointed me in the right direction, with the height or volume modifier.
Maybe this helps people with a similar challenge: I’ve used a Height Range Modifier, specified a range corresponding with 1-200 layers, and played around with inner- and outer wall speed. Awesome functionality!
In Preview mode (of Orca slicer), selecting the Layer Time view, I aimed for layers 1-200 to have a layer time similar to that when you go to filament settings and choose a Max fan speed threshold, Layer time of 125s, as outlined in my original post.
