Hello there,
I’m just wondering if i need to do pressure advanced calibration on the U1 for third party filament inside the slicer or if automatic flow calibration does all the job.
I saw that there are pressure advanced values set in SnapSpeed PLA Profiles of the Slicer. From the infomation shown inside the slicer the automatically created values will be overwritten if values are set inside the slicer.
Anyone from Snapmaker please can clarify this. Thanks 
I do this only on u1 every time change filament.
It overrides PA with K validity calculates during Dynamic Flow Calibration, and fallback on this value if that process fails. Confirmed this in the logs.
Personally, I don’t use dynamic flow, as it’s waste of time and filament. Only use it one time when I am calibrating filament and then save that value in slicer.
What @nik4223 says I think is the best way.
The printer “forgets” the measured pressure advance (“Dynamic flow calibration”) when you unload. Then goes back to either the slicer value if provided, or its default value if not.
But you can also either measure it yourself if you know how and save it to material settings in your slicer. Or watch the command terminal in fluidd while the U1 is measuring it to see what it thinks is best and save that.
Doing it this way you can have a good value without waiting to measure it every time you load. Or only use the measurement for strange filaments you don’t use often or if you’re trying to be precise on the fly.
(It’s said that even dyes can affect the PA, which I guess is true. I’ve personally never seen it very so much based on color alone too bother me as long as the material is right. But I’m not extremely picky.)
Whenever you ask the printer to measure it, that will override whatever the slicer told it.
Thanks everyone.
So this Info Message inside the slicer is wrong. Or at least missleading. Maybe this should be changed in the future.
This might be the default orca message.
