Hi, Is there a way to set support interface temperature other than print temperature?
As far as I know, only if you enforce a different filament (profile) to be used, i.e. select a different support filament (even if it is the same filament with a different profile).

I see, it seems a good solution. I want to try different temps for support interface in order to check if it has effect of easy removal.
have a look at thishttps://www.youtube.com/watch?v=8oWAacnuViU
My aim is to use the same filament for support interface. Maybe printing the support interface at a lower temperature may help easy removal. I ll test if it works.
A nice thought but be aware of the hidden traps 
What is the goal here?
The easy removal of supports and interface layer from the model?
Or a good enough bond to the interface layer to get the best possible surface for things like angled support faces?
It does not really matter at what temp you print the interface layer if the same filament is used for the rest of the model.
It is the layer that follows the interface layer that creates the bond (or not) with the model
Means that while this change might provide a better separation from the support below it will have little to no effect on how easy or not it is to get this interface layer removed from the model.
Personally I find it more practical to adjust the interface layer to my, the models and/or the filaments needs.
Take PLA:
I tune the interface pattern, spacing and distance to the model.
With that I control how easy or hard the removal might be.
More often than not a well bridged and more or less horizontal and flat surface will come out as good or even better than a well supported one after the removal of those supports - go figure, we rarely even try…
I can have my PLA supports snap off without issues, even from things like pointy claws on a dragon model or such.
But I also have no issues making them strong enough to require sanding off parts or all of the interface layer…
All a matter of getting the settings and tuning right…
Sure plastics like ABS, Nylon PETG can be a pain to get right as we often require a stronger interface bond to avoid problems with warping or bond strength with the supports.
If you do want to keep playing with different temps for the interface layer the only real way is to use the same or similar roll in another AMS slot.
Defeating the purpose a bit by wasting a lot of filament during those purge runs.
So do reduce those flush amounts to zero if you use the same filament anyway.
I have not checked how well commented the G-code it that you can export to a file.
But if the interface layer sections are properly commented you could use a good and free editor like Notepad++ to locate those comments and create a simple command sequence to add the required G-code for a temperature change.
Only problem with this approach and no filament change is the unavoidable delay …
If the model prints at 235 degrees while the interface layer is supposed to print at just 210 than you HAVE TO consider the time it takes not just for the hotend to cool down but also for the filament inside the melting chamber.
Quite impossible to get this done without a severe impact on temperature related print issues…

Not sure if this is the best approach as the method I described will need to spools anyway. So you might as well go for the dissimat interface material approach (PETG for PLA and vice versa). Concentric interface, 0mm z-distance. That is hard to beat in my experience.

I generally print functional parts and want best possible surface. I did a test with the same filament with different profile (20C lower temp) and the support interface was printed in lower temperature although transition between profiles was not perfect because the nozzle needs some delay to adjust the temperature.
But i didnt see much difference between the same profile and different profile prints. I know that using different types of filament for smooth supports is better but i dont have an AMS and it makes the print duration much longer. Thanks for helps
