You can Manually Edit K Values now!

Bambu Lab Software Bambu Studio

I did a factory reset on my X1C today. I haven’t done one since I got it in November and thought I would try it to see if it improves my prints.

I did the factory reset and since it erases all K values, I did a flow dynamics calibration for the filaments in my AMS. After saving the calibration I clicked “Manage Results” and noticed that there was now an edit button beside each of the filaments. You can edit the K value or the name of the preset. I just looked at the “Manage Results” in both Bambu Studio and Orca before doing the factory reset and neither had an Edit button for either new or old calibrations. You can’t add new presets without doing a calibration, but you can edit any that currently exist.

Thought i was going senile with buttons appearing as if by magic whilst printing the A1 Mini , due to pla matte having a k factor of zero

Apparently there is a a bit of a hack, if you know all your filament values, (screenshot etc) - then after a factory reset\k wipe… In the middle of a huge long print but I might do a test before another factory reset.

Process.

  1. Start the calibration of your filament.
  2. Cancel\stop the calibreation - it records a (false) result anyhow
  3. Edit that k-value for that filament against your screenshot\spreadsheet.

Test I plan

  • Calibrate fully a new filament I havent done.
  • Do a clean succesfull print
  • Record that filament and result
  • Manage results - DELETE that full calibration filament, k value etc etc
  • Start and cancel a new calibration, possibly after a printer and bambu studio restart
  • See if I can edit the k value previously recorded and do a succesful clean print.

Thanks for the information. I took screenshots of my old values before doing the factory reset in the hopes that there might be a way to re-add them. I will try adding my old K values and let you know if it works.

I did a test and confirmed that it works, but only on the Manual Calibration page one filament at a time. I was hoping it would work with the Auto-Calibration page since you can do four at a time but it didn’t.

I started the manual calibration and immediately cancelled it, then changed the name and K value to one of my old values. Make sure on the first page that you select the filament that matches the one you are adding (Generic PLA, Bambu PLA, etc.), so that it works properly when you use the filament and configure the type. For example, when you select Generic PLA, the K factor option you added will show up in the K value list specific to Generic PLA.

Yes, should have mentioned that. Best we can home for at the moment, I hope to be able to use that to store in ORCA manually as well, but if I get any wierd printing either in Studio, or Orca, I will know something is off and do a full proper calibration.

I calibrate all my filaments before printing. Initially, I perform an automatic calibration and store the K value under the filament’s name and color. Afterward, I print a test sample with multiple layer heights to analyze how light passes through the filament (useful for light boxes).

Is there a way to start the test print, enable “Flow Dynamics Calibration,” and then retrieve the K value for storage? This would allow me to combine both steps and avoid running the calibration separately.

Bump - Did you ever figure this out? It would be great to save the auto calibration k value to the filament profile so that it doesn’t have to waste filament every time and you don’t have to manually calibrate (and also waste filament).
