i am currently struggling with a print and since i am relativly new to BambuLab, i hope someone can help me to solve this Problem.
In the Picture you can see, that this one part uses different print speed and flow rate. So I tried to slice it alone and it still doesnt print every layer with same speed and flow rate. The only solution I found is to reduce the overall print speed extremly, but this cant be the only solution. Also a modifier block doesnt work. I think I am missing something here…
Speed is a function of what’s being printed. You can’t make slower layers go faster relative to faster layers, the slicer is already maxing out that speed. You have to slow down the faster layers relative to the slower layers. And yeah, it could be a pretty significant slow down.
That being said, this appears to be a uniform cylinder. It should be using the same flow rate for the entire thing.
For the first one, I’m not sure if I completely understand you. Do you mean the time it takes to print a layer or the speed at which the layer is printed?
Exactly, but I can’t change it unless I set the flow rate for the whole cylinder ridiculously low. Why can’t I just use the print speed and flow rate of the upper layers for the entire print?
The slicer is deciding how fast to go based on speed settings and filament flow rate. I can’t tell you why the lower layers are printing slower if it’s a uniform cylinder. But there’s something about the model that requires those layers to be slower. There’s no way to speed them up unless you determine why the geometry requires the lower speed and correct that problem. Otherwise, you’re only option is to slow down the faster layers until they’re the same speed as the slower layers.
Really, you need to figure out why the slicer is insisting on less flow lower down vs. higher up.
I just had a second look at it, and it only happens because I am downscaling it in the x and y directions. The more I reduce its size, the more apparent the effect becomes.
I mean, it makes sense to go slower in smaller circles, but why should it be a problem when it works faster in the upper layers?
