Hi everyone, I spent some time searching for this topic and didn’t have luck finding this exact issue posted, so apologies if its already been asked and its a repeat. I got into larger prints (usually print smaller, less complex things) with many branches, and came across my first failure(6 hours in 
) where a branch snapped. Inspecting it I noticed the supports were not correctly built, likely leading to a weak point. The filament is calibrated and I’ve never had issues with the print itself, only the supports. I’m using a P1S.
Disclaimer: I’m using adaptive layering for my print to get good quality, so not sure if that’s a contributing factor.
I first used the default tree support settings which led to this failure, and I’m in the process of printing again 
, having made 2 changes and so far the supports seem to be much better in addressing this(not perfect, but much better).
- I reduced the “Branch Angle” from default 45 degrees to 35.
- Reduced the speed of the supports from default 150mm/s down to 100mm/s.
- On both runs I ensured the support walls were set at the max of 2 (wish I could add a 3rd!)
For the more experienced folks here, which of those 2 settings would make the biggest difference for correcting this particular issue?
My gut says the speed is a factor more than the angle but figured I´d change both to try and avoid another failure 6+hrs in, those hurt! (The default speed is “high” but I guess it assumes it’s for smaller prints which to its credit I´ve yet to encounter a failure till now).
UPDATE: 2nd attempt of a 25hr print was successful! With those 2 changes it did the trick. My question stands, for general knowledge and learning.
As I mentioned, the trees weren’t great, but MUCH better. Very sturdy.
