Pressure Advance Data Field
Please include a data field for PA (Pressure Advance for Klipper users) Typical setting expected is 0 to 1.000 for PA.
This setting is spool specific and goes hand in hand with flow % for an individual spool.
Believe this was first mentioned by @locki-cz in issue #10.
Also, thanks for moving this project forward! Keep up the good work!
Hi, first, I do appreciate your project. IMO , PA, flow, and other print parameters are not only spool specific but also printer/toolhead/nozzle diameter dependant. It would be nice to store this datas according to a toolhead reference. Till now I use a Klipper macro to store filament specific values in the printer https://github.com/fbeauKmi/V2.3934/blob/main/klipper_config/macros/helpers/db_filament.cfg and call them in print_start. I planned to do to moonraker plugin but it's a bit out of my skills. It would be nice to that in spoolman
Perhaps a new item type is in order then? Like a configuration set. You could then add new configs to specific combinations of vendor, filament, printer, toolhead, nozzle.
Having a system like this instead of having parameters like "override extruder temperature" on the filament object would make it a lot more flexible.
I created a quick mockup, would this make sense?
That looks really nice !. I am not sure to understand exactly how it works. But IMO, Pressure advance and extrude factor (Flow rate), for example, are spool related. I experienced filament : same brand/vendors/color with different values for PA and EM. Does this criterias would be accessible or could be modified thru moonraker ? I use much more parameters but I have to admit it is overkill for many users. Here the list currently running on a printer : eg : Settings for ASA_AZUREFILM: // _ bed_temp : 105.0 // _ chamber_min_temp : 30 (default) // _ chamber_temp : 60 (default) // _ extrude_factor : 0.95653 // _ extruder_temp : 250.0 // _ fan_speed : 50.0 // _ filament_sensor : 1.0 (default) // _ filter_speed : 0.5 (default) // _ max_flow : 26.0 // _ pa_smooth_time : 0.025 // _ pressure_advance : 0.035 // _ retract_length : 0.4 // _ retract_speed : 35.0 // _ soak_delay : 30.0 (default) // _ unretract_extra_length : 0.0 (default) // _ unretract_speed : 35.0 // _ z_adjust : 0.0 (default)
BTW, let me know if I can help !
I realized that a lot of these settings must be tuned in the slicer, and overriding gcodes will be too late. So perhaps a slicer integration would be necessary then as well, which sounds like a daunting task given how many different slicers there are etc.

Correct, really the only overrides in my personal workflow are PA and the occasional extruder or bed temperature overrides after a print has been started but I forgot to change them. PA does change however based on nozzle size. Would be good to maybe capture that.
