I have an A1 mini, and 99% of the stuff I’ve printed has come out perfectly. I’ve had a few prints, however, that seem to have had some warping issues (at least I think that’s the right term) in the corners. Specifically, the boxes printed for the lithophanes from MakerWorld. They still end up printing okay, but the four corners are visibly lifted off the build plate by the time the print is finished. I’m printing in Bambu PLA basic on the SuperTack plate, and I’m just using all the default settings. I don’t know enough about 3D printing to know what might be causing the issue and if there is a specific setting I should try changing. I kind of assumed I wouldn’t need to change anything since I was using Bambu filament with a model from Bambu. I’d appreciate any suggestions on what I can try to fix the issue for the next time I print one of these.
Temperature in the surroundings, drafts, time to print, structure of the model, changes in the structure as it prints and more are the causes.
There is rarely a magic solution.
You could start by adding mouse ears on the corners (right of toolbar in the prepare tab), these serve to provide more contact and slightly push heat out.
You can change the bed temperature and turn off the fan for the first few layers.
It is about experimentation.
We are as close as it has ever been to having a solution that requires no tweaking to achieve perfection. But, we are not all the way to entirely unattended and perfect output guarantees.
when it has popped up in my experience. window is open, or, i ran me grubby fingers on it and forgot it deserved a drink of ipa
I had this issue and started forcing Outer Brim on most prints, it’s a bit more annoying to remove after the print is done but it helps a lot avoiding the lifted corners
Just had this issue with the supertack and a very large print (corner to corner large).
Luckily it’s just for me & a functional print, so not too bothered… But first time over seen the bed lift because of the forces
I know it’s not a fault as the left side, which does not have the print is fine
Glad to read I need to think about stuff when pushing the corners like this - so thanks to the previous person for giving some great tips
Wow that is good bed adhesion.
One thing I will say about the supertack… took a few prints and cleaning to get it “right”, but now… Jesus that thing is amazing at sticking stuff to it.
I won’t use it for small prints for that reason.
I also wonder if that is the reason why this is happening… It’s thinner and a little more flexible to the other plates, so has slightly less magnetic stick to it, as compared to the pei sheets.
At the start of using supertack I couldn’t get it to be reliable… now it works like a trooper and is my goto plate
