Howdy mates,
When I print PetG, the Supports sticks to much to the print. Some support bits are stuck on the print as hard as the print itself or even harder if thats even possible…
I changed TopZ/BottomZ distance to 0,35 that some Bambu printer Gurus recommended on Youtube… it helped a tad butt the support/print still sticks together way to agressive… (I ripped apart some prints)
Could anyone give me some advice on this I would be utmost greatful for your help mates!
May the force be with you!

Glue stick or Bambu liquid glue helps with excessive adhesion strength.
How do I get the glue stick between the support and the printed object?

You do have a AMS so you can print supports with a different material that does not stick to petg.
Printing time will be longer though.

Well yes, but I mean there must be some tweaks that can be made to optimize the relation between the support trees and the printed objects.
Something happened when I changed the above mentioned settings from ,2 to ,35…
So my figuring is that some skilled brain here might know the ways around this maze of settings?

Ah, okay, I missed that you were talking about the support sticking to the part.
If you check other threads regarding issues while printing PETG, there are a few discussing a problem, which is beneficial for PETG support removal.
When printing PETG with too low temperature, layer adhesion gets really bad → that’s exactly what you want, right? But only in areas, where support and object are close to each other, that is in the interface layer. Now the question is, how to configure different temperatures for printing the object and support? I couldn’t find any such setting in Bambu Studio or Cura.
Hopefully Bambu Studio / Orca / Cura adds this feature to the slicer settings

I find sometimes tree supports are easier to remove. Check and see if they fit your model’s geometry. Normal Snug supports can sometimes be easier to remove as well, but tend to be very close to your model (hence the name “Snug”) so be sure they don’t melt together, which would be totally counterproductive.
I almost always change the X/Y Spacing to .50. This gives you a larger gap from the model to the support so they don’t fuse together on accident (Bambu Studio does allow that oddly). Obviously, there is no printer/filament combo that can’t bridge that gap very well. I’d almost suggest this as a default. As a last resort you could also try .50 on the top gap too, but that will affect the surface finish of the overhang.
@Silverbullit did you ever figure out what the best settings are? I’m having a similar issue with a very basic part. But I’ve had to scrap several pieces so far. I’ve tried PLA for the interface layer and Z distance to 0, but I’m still having no luck.
