I had a BBL P1S until mid January and decided to sell it.
Now as I got a new P1S delivered there is the question whether I have to calibrate all filaments new? Filament definition is still there (I guess in the BambuStudio installation). But there is no calibration data available. I calibrated all filaments in use. I still have the SD-Card from the old printer, but did not use it in the new printer.
