However if the first layer has defects, you want to eliminate them because they impact overall print quality. “First layer” settings have very little impact on the overall print time, so “tweaking” them is unlikely to result in any substantial difference. I like to check on what is the “bottleneck” in my print, and try to make improvements where they have the most impact. Conversely, if your prints are perfect, dial in your speed settings. If something is printing too fast, slow it down. However you do it, the bottom line is you are changing the speed for a given trace of filament, which you can see graphically. Then do “dial in” that setting for the PETG filament, I can choose to lower max volumetric. I would first establish what speed works in my print by just changing it directly in the process settings. If you keep lowering the max volumetric speed, you will eventually see that speed limit “kick in” and override the process level settings.įor example in a PETG print I am having problems with inner/outer walls printing “too fast”. It is easy to see the effect of changes in your print, just change to “speed” and you see colour coded by speed. As the hot nozzle travels over the just printed top layer, it flattens any plastic that might have curled up. But I suggest you REALLY don’t want to do this the max volumetric speed is your “friend” so that you don’t have to change the “process” level speed settings as much.īut using a test model to try to establish an “optimum” for this is misguided. How to make top surfaces smooth with PrusaSlicer How does ironing work Ironing smooths flat top surfaces by running a special second infill phase in the same layer. ![]() So if you want to increase the volumetric speed to some huge value, you will never “use” it at all, the other speed settings will kick in first. Once the speed has reached a “steady state” the acceleration setting has no effect. inner wall, outer wall, infill, etc.Īcceleration setting affect how quickly speed changes apply, when the printer is moving from one speed to another. You can change the speeds in the “process” profile as well, and you have more control over the “context” e.g. Volumetric speed is kind of a master “speed limit” that lives in the filament profile, and by default this is the same profile regardless of nozzle size.
