It is labeled as an "override" to try to clearly show that it will indeed override other settings. The situation you describe would require the user to tell the software things that conflict. Saying I want every layer to have the fan on if it is below a certain time threshold should apply to that whole process.
So, if I understand correctly, if I am printing with ABS and have the fan layer control speed on the cooling tab on the left set to Layer 1 Speed 0 to indicate NO fan at all for any layer in the entire print, the override is still going to turn on the fan when it thinks it is needed even though I set the fan to "off" essentially.
So setting the overall layer fan speed to zero is pointless since the override will do what it wants?
The fan speed override is also only really valid for printers with variable speed fan capabilities.
The override serves no real purpose for printers like a Flashforge Creator Pro that do not have variable speed fan capabilities. The fan is either on or off.
So S3D determines that a layer print time on an ABS print is below the threshold and turns the fan on, which will be full power, and wrecks the print due to excessive cooling.
I really think someone has created a "fix" for a problem that wasn't there.
The override should only be exactly that. The override should only be able to be activate if a general fan speed has been set on the cooling tab.
The setting that turns on the fan according to a minimum layer time threshold and is labeled as an override will override the set points you have set in the temperature tab. If you wish to use manual control rather than automated overrides.... turn off the override setting and your manual set points will no longer be overridden.
No offense but this is just plain stupid. If I set the fan speed for all layers to zero I still have to go disable the override to tell it "NO, really, I meant NO fan".
You have taken something that really wasn't an issue and have now made it one.
You are treating the fan override like the speed override but the difference is that "print speed" is mandatory so it is always on or NO PRINT unlike the fan which may be set on only for specific layers.
So, if I do not want ANY fan for my first layer, which is a given for almost all prints, I have to set layer 1 at 0 and also disable the override. But what if I want the override active after layer 1? Now I have to make a second process? Or I have to modify the start script to kill the fan for layer 1.
No matter what you have taken something that was mostly ok and overly complicated it and rendered other settings mostly useles.
What is the point in being able to set the overall layer fan speed to zero if it is just going to get overridden? Might as well do away with the layer speed setpoints setting alltogether.
Sorry to say but 4.1 and 4.1.1 really have been big disappointments.
