Just so I’m making sure I understand, if I want fully dynamic flow calibration:
- I should uncheck “Enable Pressure Advance” under each of the filament profiles I use
- After each time I load a filament into a toolhead, for my first print, I should check “Extrusion Flow Calibrate”
- As long as I don’t use a filament profile on that toolhead which has “Enable pressure advance” enabled, or unload that toolhead, it will preserve my dynamically calculated pressure advance value for repeated prints
- None of this has anything to do with “Flow Ratio” which I should still tune using a traditional orca “Flow Rate → YOLO” calibration test
One question I have is, while performing a flow rate test itself, should I enable pressure advance or not? Should I use dynamic flow calibration or not? Or does it not matter?
EDIT I just did this and while watching the logs in fluidd, it seems like my dynamic flow calibration can’t even measure the value on its own
11:40:11 // start extruding
11:40:11 // measure k: 0.03800
11:40:42 // measure area: -552799.00000
11:40:42 // measure k: 0.06200
11:41:23 // measure area: -1647190.00000
11:41:23 // abort calibration: out_of_range
11:41:23 // flow k is out of range, use default value:0.05
