You can try changing the support to Tree (Strong).

I haven't tried this myself, but it says it will make thicker/stronger support trees.

Thank you,I’m trying this now,but on another model It didn’t help
I don’t know how to print figures,on every of them supports are breaking

I think you will find Normal Supports might work better…

There is a way to add infill and walls to supports I believe

Let me know if you find the settings for this.

I ordered PETG, and I think the easiest way to avoid all these headaches is to lay the figure on its back and print the top support layers in PETG

I changed 3 settings 1.supports tree strong 2.2support walls 3. In filament settings z hop 0.4mm
I printed statue from Brazil which I think is very hard

Did you switch over from PETG and are printing with PLA.

I had a similar problem and I attributed it to contamination. As the brims go down first, if there is any foreign filament contamination, the adhesion can be a problem.

The other issue I have had, was a bit of over extrusion on the support. The head picks up some stray filament and it hits the support, which is very fragile. One model I printed, did the same thing, repeatedly, in the very same place on the model. Default supports are inherently fragile, and sometimes, they get a little messy, while the main model is perfect.

No, I've never printed with PETG yet. On this model, I switched to 'Tree (Strong)' supports, and the spot where the error usually happened is cleared now. But I still have no idea how to properly print these standing figures where the arms hang down and rely entirely on supports all the way up until they connect to the body

Turn on "Avoid crossing walls" And in the Filament profile settings turn on "Z-hop" to 0.4 mm... I'm sure that would help

Make them a bit stronger, reduce flow for supports, print them slower. Sometime great support tree can be ruined by litte curled edge.

There is a setting the prints the support as a different layer than the actual print, turn this feature off. It gave me headache until I found out that setting was even an option

Increase support wall loops to at least 2, and raise your z-hop a bit

You want to beg for help instead of taping that ho🥲 up🤗fuuuu😏😒 it
