I'll make one that does't need supports soon!

Hey, so sorry you had to go through that. I used a textured bed and there should be brims around the supports. Did the profile not include the brims around supports? First time doing this so your feedback means a lot!

As for the AMS being optimised, I did my best. The flushing volume multiplier is set to .65 and the filament waste is due to the brown branch intersecting with the tree leaves. That is also why the print time is 4hrs. I found it to be worth it as the tree looks really good with my print on the a1 mini

it did have the brim but it still got knocked off. I just printed a bunch of tiny clips before that and am currently printing something else with no adhesion problems so I kinda doubt that my print bed (also textured pei) is the problem. still that might just be a problem with my printer as "it worked previously and it works now" is in no way a guarantee. what I would actually look into if I were you is if you can't decrease either the purge volume with each colour change or decrease the purge tower volume. it seemed to me that you're purging quite a bit more material than you actually need to.
