Hi all,
Just trying to learn a bit more about the printer and software.
When I was reading about the “slowdown for overhangs” wiki post I did as it suggested, which was to slice the object then look at the speed of each layer. When it got to the overhang areas it slowed down to the exact speeds defined in the “slowdown of overhangs” section as expected, all good so far.
However, I also noticed that it was slowing down (or speeding up) at different times for different layers. I could match most of these speeds (of what the printer was actually doing) to the speeds in Bambu Studio for those sections – an outer wall was printing at speed 300 for example, which matched up to my outer wall speed settings in Studio. But the slicer was showing that the printer would print at some speeds that I could not match to the software and the following images capture this:
In this first image you can see when doing the tower part, it starts off green (which are speeds around 200), then it goes yellow for a few layer, then pink (indicating a speed of around 20).
I had a look at one of the layers and stepped through the sequence. In the image below you can see the whole layer is speed 79 except for the overhang. I mention the overhang so that you can see it is different to the rest of the layer and therefore the 79 speed is not related to overhangs and has nothing to do with my overhang settings (so don’t tell me to look there 
).
My questions are:
-
Firstly, I cannot see any section in my software that would cause this to drop to speed 79 (even with percentage based fields), so why does it do this, and where does it come from?
-
The entire layer is always the same speed, but the next layer up is a bit faster, but again is always the same speed for the whole layer. What determines the increase/decrease for the speed in general? The only thing I could think of is that it has something to do with amount filament extruded at a given time to cover the whole area evenly.
-
Interestingly, this layer also does the infills at 79, when in my software they are set to 250. Why would it do this, or is this a bug I have found (see last image below to show this)?
Thanks,
