Get estimation data via CLI

[sguter90]

I want to get estimation data of a print via CLI to automate stuff (e.g. get print time for all files in a directory or building a web interface)

Is your feature request related to a problem? Please describe. https://github.com/bambulab/BambuStudio/issues/76 introduced price estimation

Describe the solution you'd like I would like to use the CLI to get filiament (m/g), cost, model printing time and total time as displayed in the preview tab. (maybe more if it makes sense) With the PrusaSlicer I do something like this (on MacOS):

/Applications/Original\ Prusa\ Drivers/PrusaSlicer.app/Contents/MacOS/PrusaSlicer --export-gcode --layer-height 0.4 --output example.gcode ./example.stl

This command will generate the gcode which includes the data as comments:

...
; filament used [mm] = 14664.38
; filament used [cm3] = 35.27
; total filament used [g] = 0.00
; total filament cost = 0.00
; estimated printing time (normal mode) = 2h 36m 25s
...

I'm not sure if the 3mf format can include this information somehow.
This would be probably the simplest solution.
If this isn't possible maybe adding an additional CLI parameter like --export-estimations filepath.json can also be an option.

Describe alternatives you've considered I tried to export the sliced file as 3mf file, replaced the 3mf extension with "zip" and searched for the data but couldn't find it.
I've searched for official profiles which can be imported to PrucaSlicer (but actually I want to use BambuLab Studio for this).

Additional context Estimation data in the preview tab of the GUI:

As long as the feature is not available, you can do all sorts of Automations like this, using the Smart Package Robot. He can also click Buttons in the GUI. He can directly read all Data from the GUI. You can get it here. Smart Package Robot PS: Its not Freeware but commercial.

[sguter90]

@theogott Thanks for your suggestion, but I mainly use MacOS and Linux.
Even if the Smart Package Robot would work on e.g. Linux this would need a desktop environment (which I don't have on most of my Linux machines).
Setting up an additional Windows VM or something like that is an overkill in my opinion.
This is the reason why this will not work for me.

[theogott]

I understand, and agree that an open Interface from Bambu Studio will be an advantage as it will enable also a lot more Integrations.

[FOREVEREALIZE]

So I found kind of a workaround:

.3mf files are just ZIP files in disguise. One can unzip them and, in the files within, there's a folder called Metadata. Inside this folder, the slice_info.config file, which is, once again, an XML file in disguise, contains the filament tag which, as one of its atributes, has used_m (millimeters used) and used_g.

If you know the price per kilogram, you can calculate the cost as: price_kg / 1000 * used_g.

Additionally, the Price per Kilogram can be obtained from the GCode that Bambu Studio gives, in the filament_cost field between the CONFIG_BLOCK_START and CONFIG_BLOCK_END

Hope this helps!

[!WARNING] Sometimes, when slicing with the CLI, the used_g field will be 0. In that case, the filament_density and filament_diameter fields between the CONFIG_BLOCK_START and CONFIG_BLOCK_END (or, in this case, between the HEADER_BLOCK_START and HEADER_BLOCK_END as well) in the GCode and the used_m from the slice_info.config (which does appear to always be filled) can be used to calculate the total grams like so: PI * (filament_diameter / 2 * 10^-3)^2 * used_m * 10^6 * filament_density (calculate filament radius in m, then calculate filament volume in m³, convert to cm³, and calculate density in g)

still not able to utilize the cli to slice a given stl/3mf file and gets its print time and filament estimate anyone has found a solution ?

@FOREVEREALIZE my 3mf files Metadata/slice_info.config doesnt have those fields

Are you using the sliced 3mf (exported after setting config and slicing) or just “geometry” 3mf (as in downloaded from Maker World)?

no its not downloaded from maker world im slicing a model that i created that i have as stl in my system using this cli command the .json files are the example files from https://github.com/bambulab/BambuStudio/wiki/Command-Line-Usage

./Bambu_Studio_linux_fedora-v01.09.07.52.AppImage --arrange 3 --load-settings "machine.json;process.json" --load-filaments "filament.json" --debug 2 --export-3mf output_test.3mf ./<redacted>.stl --orient 1

ran in my ubuntu 20.04 machine

That's odd, I've just tried it with my BambuStudio and it works. I am running a bit of an older version (maybe one or two releases) so that might be it. Try a couple older versions (assuming the one you are using is latest. If it's not, try the last couple releases).

Thanks, will give it a shot today once I get some time and update here, if possible can you show an example of how that file would be ?

Sure! Here is the Bambu Filament Spool (not original one) sliced for the X1C 0.4mm nozzle with Generic PLA as the filament.

(It's in a zip file because GitHub doesn't like .config files...)

Thanks, also how should I go about getting json files for my printer which is the a1 and it's standard configs ? is there a way or place to download those configurations ? filament, process etc

They are here, in this repo:

• Printer profile for the A1 (not Mini) is here (with 0.4 mm nozzle): resources/profiles/BBL/machine/Bambu Lab A1 0.4 nozzle.json
• Processes for BBL printers are here: resources/profiles/BBL/process

EDITED: Never mind got it working didnt have the slice flag in it.... so the part didnt get slices at that point of time thanks
