I just tried this firmware and the latest version of Bambu Studio.
I calibrated two filaments for K-Value - a silk PLA and a new roll of PETG-CF (something I have not printed yet) and got the expected values of 0.02 for PLA and 0.04 for PETG-CF (though to be honest, I could go with 0.02 or 0.04 for both, those calibration lines are too short I think)
And there’s a big issue now (or at least two)
There are huuuge gaps wherever lines should connect
I did the same model with both PLA and PETG-CF and got the same behaviour. I tried lowering the K-Value for the PETG-CF to 0.02 with no effect.
I also resliced this model with OrcaSlicer (with Pressure advance disabled) and got the same result.
I am continuing to investigate, I just power cycled the printer and will retry, then I’ll try using OrcaSlicer with K set to 0.02 in the filament settings and PA enabled, then I’ll try automatic flow rate calibration.
I will update this post, this is just a heads up for anybody seeing similiar issues. Is nobody else seeing this?
And there’s another issue, once you save one filament profile to the printer, you are forced to use it for any material of that type. There’s no way to “unselect” my saved calibration when putting in a different PLA. This is a mess.
