Hello all, was wondering if someone would be so kind to help me troubleshoot an issue. It seems all of a sudden that my tree supports are incredibly difficult to remove, so much so I have to pry them off with a screwdriver which just causes unnecessary damage.
I’m still fairly new to the Bambu Studios software, but this has not really been a issue with pervious prints in the last 6 months that I’ve been using the A1. These last few prints have been a nightmare when removing these supports. Here’s a screen grab of my current settings, I don’t usually change anything from the default settings until I understand what does what, so I haven’t really messed with these. Any help would be appreciated. Thank you!
There’s a good discussion here somewhere about support things but you could try opening up your top z-axis spacing. That can get you a rougher model but make them easier to remove.
It’s more radical but there is water soluble support that can be used as the interface (it’s a little expensive) and dissolve away after printing to free it.
But others know lots more about this than me. You’ll get a good answer.
I had a similar problem lately & found out my bed was no longer level, it was too close. Something you might have to look into if it’s happening on other prints.
I have found that if the supports are not removed soon after printing, then can be hard to remove.
One issue I dealt with was a very long print (4+ hours), so even though I went to remove the supports soon after printing, the supports at the lower layers had been sitting there for a few hours.
Tree support does appear to have become harder to remove recently.
On my smaller models I use the classic rather than tree support. I far prefer tree support though.
If you have an AMS and some PETG (assuming you printed in PLA), you could use the PETG as a support interface, it builds the support using PLA until it gets close to the model and then swaps to the PETG as PLA doesn’t stick to it sufficiently, just enough to allow the model to use it as structure.
This reduces the filament swapping and should provide a smooth contact point where the support was.
Thanks all, I use Bambu Basic PLA. It’s weird, I prefer tree supports also, and all the times I’ve used them in the last few months, no issues. This just started happening in the last couple weeks, real bummer because I haven’t changed a single thing, been using mostly presets.
My house is 77 degrees with 25% humidity (even though here in Arizona it’s a cool 108 outside).
Like I mentioned earlier, not been an issue in the 6 months I’ve been printing, the temperature and humidity have been constant for the most part in my house, just started happening after this last update. Not saying it’s the update, maybe there’s an issue with the batch of filament I ordered a few weeks ago. 15 cases of Bambu PLA Basic, but weird it’s only a support issue. It is what it is, just gonna require a little more post work.
You may be correct. However filament isn’t always dry from the factory. I would assume that it wouldn’t affect just the supports, but it’s a possiblity.
I’m banging my head as to why it would just be supports, and why it would have just started. I had the same update and have had no issues. My daughters A1 Mini is on beta and uses the same version of Studio with no change as well.
The only real thing would be somehow the settings have changed on support. If you have the AMS and any PETG try using it for a small print as support material. See how that comes out.
Great info. I didn’t know about the exact slicer process/sequence. I did know about PLA & PETG as support and vice versa. Just never needed it, my supports usually just pull off easily. Anyway I got intrigued, and tried it this morning. It works nicely. This is Bambu PETG-HF and PLA silk for support. Thanks for the info.
Well, after chatting with customer service, seems there is an issue. They state,
“We have received feedback from a small number of users regarding the new version of Bambu Studio, which, due to changes in slicing and printer path logic, may have some impact on support structures. We kindly ask you to confirm your Bambu Studio version and suggest that you try using a version prior to 1.8.4 to see if the issue improves. We are working hard to improve and optimize the software, finding the right balance and best solutions. Thank you for your understanding and cooperation.”
So before I revert back to the previous version, I guess I’ll increase the Top Z Distance and Support Object XY Distance and see if messing with those numbers helps.
