Flow dynamics and flow rate

Bambu Lab H2D
1

Hello all,

I’m somewhat confused by the filament calibrations. I watched some videos how to do it and read quite a bit about it as well. However, I’m still not sure how it works. The flow dynamics seem to be straight forward. Run the calibration and choose the profile (k-value) either in Bambu Studio under “Device” or directly on the printer. Or do I miss something here?

For the flow rate calibration, it generates a new preset after the calibration. Can’t I save the results in the existing preset? Because now I have two of them and have to check every time that I activate the correct one:

Another question: On the printer, I can only select my “basic” profiles. Are the settings only relevant for slicing, and as long as the correct filament is loaded everything is fine? Because also in Bambu Studio it just says that the “Basic” filament is loaded, and under “user presets” the calibrated preset is selected.

Last question: Is there a way to rename the preset, or do I have to create a copy and delete the old one?

Just delete the “Calibrated” before pressing save and it’ll save it to your existing profile.

But then there’s no way to track while profiles you’ve calibrated and which ones you haven’t unless you make a spreadsheet or something. We should be able to CHANGE the name of the profile to add the word Calibrated or there should be a flag on the profile name like an icon or something that easily shows you its calibration status. Filament management in Studio is VERY clunky!

Yes as long as you have the right filament selected before you slice it you are good to go.

No I have not found a way to just edit the name so I create a new one and delete the old one.

Also related; There’s a guide from 2024 on the forum on how to add calibrated filaments to the device tab ams filament settings but I have not been able to achieve it. After calibration the filament just gets added under generic pla or generic petg and then the calibrated settings are listed in the dropdown which are saved to the printer.

You can rename the profile whatever you want after it’s done calibrating.

You can also edit the JSON file for the filament.

I thought about doing this. Can I make a filament file so it will show up in the device tab’s drop-down menu list in the ams filaments selection?

the only reason you need the machine screen for filaments is to tell it which slot of ams or which nozzle, has what filament type. Say 1-abs , 2-abs, 3-abs,4-pla. You slice an object for pla, when you hit print, it will prompt you with a window saying “4-pla” meaning it “paired” the sliced filament with the installed one. DOESNT matter what profile you use, it can be custom, downloaded or bambu pla generic. AS LONG AS it has PLA as a type it will bind it to the one installed. If you have 4 pla you choose which one you want and so on.
