I did this and orca still was giving me difficulties, so for now I use the updated version of bambu till they update orca
@MrMonoWheel @Quietman, Bambu Studio 1.7.1 is allowing you to save K values to the machineâs/slicerâs profile for that type of filament. Was actually very painless. Unfortunately, the Bambu Studio functionality isnât great when running the test, at least for me. It appears to fail and disconnect when sending the file to the printer but if youâre patient, it will go and start after a couple of minutes (literally 2 minutes or so). After that, you choose and input the K value in the slicer calibration field and it sticks. No GCode changes needed, no manually updating.
Now, if they would only allow that for the flow ratio. Iâm finding the PLA CF a pretty long way off. I can save a new profile with the good ratio, but I have to select that every time I print because it doesnât let you overwrite a factory setting. Oh well.
But the K-value / Pressure Advanced is filament specific not only filament type specific. So the right place for storage is the filament profile, like Orca Slicer handles it. Orca Slicer stores it as âpressure_advancedâ in the filament json file. I wish, Bambu Lab will merge this back to Bambu Studio in the future.
Didnât work. And another person on Github with a lot more experience with both said he couldnât get it to work either.
Yeah as someone else said, its saving for the type of filament but not for the specific profile (at least thats what I am seeing). It really isnt hard to just add the Gcode in the corresponding filament profile, in fact I prefer this since I know its being done.
Regarding the calibrations in BambuSlicer, I only use the K value calibration. To calibrate flow rate I never use the method of printing a surface and seeing which is best. I right click and add a generic cube, then print it in vase mode with 2 bottom surfaces and a flow ratio of 1. Then I use my micrometer to measure the wall thickness at 3 locations per side of the cube and take the average of all 12 values. Then I divide the requested extrusion width (slicer value usually 0.42) by the average and this gives you a value. This is your flow multiplier for the filament. You then can print 1 more cube and do the measurements again to verify accuracy, and adjust if needed.
The above method never fails me.
I was able to copy the profiles with no issues.
But i dont have the printer yet. So i dont know if there are any trouble with the gcode.
Nevertheless, i just received a pop up about a new beta from orca slicer which includes the P1S profile!
Oh you can copy it with no issues, it just doesnât show up.
Doesnât show up in mine still even though the jsons are there, and it refuses to import them if I try import config.
i copied the whole BBL folder + the P1S cover.png from the web/image folder
then you have to add a new printer in OrcaSlicer and you should be able to choose the P1S.
Well this is weird, I had to run OrcaSlicer as an administrator to get the P1S to show up. Otherwise it didnât show up in the selection list. Even then, had to select it, shut down OS and restart to get it to show up in the drop down list.
So it worked for you?
Im working with a Mac and didnt experience such a issue.
Try logging out, restart, and log back in. When profiles donât sync, this often forces a sync from the Bambu cloud for both OrcaSlicer and Studio.
See all of my previous reply.
You mean 0-015-0.02 ?
So after doing some reading the only way to get K value for new filament via Bambu studio is to not use the AMS but the spool holder. Then it will calibrate the K factor for your filament and you will see it. Then you load the filament into the AMS and set the K Factor manually. That is from everything I read and will validate later when my current print finishes.
So was this the final conclusion then? Is this the only way to find the K factor for a filament using the P1S ?
I do wish Bambu would add the Pressure Advance in each filament setting like Orca Slicer doesâŚ
Hereâs a work-around for now⌠in each filament settings, youâll need to add this manually in the Advanced tab.
Itâs last line in the image.
Please read the OPâs question and look at the screenshot. This is very obviously NOT the manual flow calibration you speak of. All it would have taken is 2 seconds of thinking to not be a snarky, know-it-all jerk/rando on some forums.
I have the same question. I see a flow calibration checkbox when going to print with the P1S in the Bambu Handy app but not in Bambu Slicer. Itâs bizarre to see this as the P1S does not have this feature available at print time and checking it does nothing.
