On my H2C printer, the PA autocalibration results are quite low. Manual calibration for PETG, for example, shows a PA of around 0.04, while the automatic one always returns 0.03…0.032. This applies to all filaments: 0.025 for the automatic calibration versus 0.055 for the manual calibration for PA-CF, for example. Has anyone tried to compare the results? I’m just curious, is it just my printer or are they all like this?
By the way, the X1C performed a very accurate PA calibration with lidar, the manual and automatic values were very close.
I noticed same difference with my H2D.
Automatic calibration result about 0.022 - 0.025
Manual calibration gave 0.035
Same issue over here on the H2D. Hopefully there is a fix or update to correct this.
So, fortunately, this is a software bug and can be fixed in future firmware updates. If the Bambu Lab engineers are willing to do so, of course…
