Hi there, I am printing some figures and I have problem with the support. I don’t want use PETG as layer between the object and the support because my AMS is still prone to get stuck with PETG in retraction.
Looking for help also about this topic.
So I will use the normal PLA+ - PLA+ setup, I added 3 layer on the top support, threshold angle 15° ( but i do with hand), the problem is that I print @0.12 and put Z distance @0.16 but still stick and sometimes hard to remove.
Any suggestion?
My settings
Why not using PVA filament as support ?
That’s a good point, many figures have a lot of branches from tree supports and I want to avoid hundreds of filament changes just for super small areas, also at least with petg when I used it as a support interface I have had a lot of retraction error. So I would try a way to use it at is best using the old school 
You should have better success setting top layer interface to 0 (no interface layers) and then adding .02 to your bottom and your top interface distance to the model.

Ok, will try this evening, bottom interface is no problem because i do always support only from plate, the other 2 I will try.
Did this help you? Did you resolve your issues? I am having a major hurdle with supports myself, I dont find using interface filament a solution, because of how many filament changes there would have to be for entire of the print.
@internetofmine, I do this on every print now and it works beautifully. Give it a try and you won’t look back.

Well I damn, it did help, thank you a lot! This is first time in 3 days this particular model of mine printed without blowing up! Could you explain me what exactly happens that this helps?
Ok, thanks for confirming that it works
Adding the .02 to the spacing between the model and the support adds just a hint of extra space and that’s the main reason for the easier removal. I like to eliminate the support layer as well between the model and support structure because it always seems to be another opportunity for sticking. Particularly, in organic models this works well.

Just checking you mean .02 on Top Z distance and Bottom Z distance? I tried this and the supports did come off better but they are still messing up the surface of the model when I remove them… Is that just unavoidable?
thanks!
@user_3840030315, yes .02 (so if the default is .20mm, make it .22mm instead). I also change the base pattern spacing for support to 1.25mm and adjust the angle to be around 45 degrees. Maybe some pictures or a bit more detail about your issue will help.

Trying to print this… can’t seem to get good settings where the supports don’t really leave a messed up surface after you remove them. I did input the settings you recommended and it’s the best so far.
@user_3840030315, that’s going to be a tricky print for sure. Definitely need to focus on tree supports for this one. The more organic the shape, the more I lean towards tree spurts supports.
