It seems that I can no longer perform calibration of “flow dynamics” or “flow rate” from Bambu Lab. It’s possible to initiate the calibrations and the printer will perform the prints, but the page in Bambu Lab remains greyed out, and saying N/A.
This stopped working when I accepted the latest firmware update on the printer today (currently 01.05.00.00, P1S). Bambu Studio says it’s the latest version (1.8.2.56).
have same isue printer status n/a cant procede by next button
Here, too. Calibration is stuck with “N/A”.
also for me the same issue
Same issue. I have the newest firmware and even the newest Studio version.
Same ! N/A and grayed out Next button after the calibration print finishes
Same isue. Also latest firmware and studio version.
Same isue Latest Firmware and Studio Version
Just tested and mine is broken as well. I have no doubt they will fix it but the question I have is, how was this not discovered in the beta test? How long was it in beta?
has any one tried orca ? is this a firmware issue or studio issue?
Well i said on the Facebook group that if i print at maximum speed i get some bloobs on the printed part even if i raise up the temperature of the hotend so not that you cannot calibrate the flow but if you print at 166% (maximum speed ) you won’t be able to finish the print
Same issue here. I hope it is fixed soon!
Same issue also. Quite working after firmware update.
Might be an obvious one, but have you power-cycled everything? (printer, Handy, and B.S.?
I’ve had this happen to me before (on previous firmware upgrades), and it was because I didn’t power/boot-cycle everything. Doing that fixed it for me in the past.
Did you fixed it ? I updated my x1 carbon and after that not printing just error
Yes, I tried power cycling everything, no improvement. Switched back to previous revision and it was working again.
I can confirm the bug. The calibration (Flow Dynamics) starts normally but when it’s finished you can not click on next (it’s grayed out). But it is possible to input the values in Device - AMS.
So yes, it’s a bug but it has a workaround.
With Flow rate it’s the same 
Is this only on Bambu Studio, or does it affect Orca Slicer too?
i must be missing something? i didnt even know this calibration menu was used for anything. yesterday i ran the flow calibration from the device page in studio before updating to the lastest firmware and i thought this was just the initial calibration i ran once when i first setup the printer… is this supposed to be ran again and again for different filaments? was this supposed to set the K value to something other than 0.02? after updating it is also greyed out for me… but like i said… ive never used it anyways. what exactly is this calibration doing and used for?
Same here and even quality of printing has become much lower, especially visible on printing of lightbox’es.
