It is related to this error, which sporadisoccurred with the model:
I have now switched off the wipe tower, although it is highly recommended to use it because of the blurring of the colours. But this was the only way I could upload the model so that it would pass the slicing test.
It looks like there is no plan what this error of the wipe tower is all about. My enquiry about the error here in the forum remained unanswered.
It would therefore be advisable for BambuLab to get involved in solving the problem. Or the error will always remain, even on “Makerworld.com”.
Thank you very much!
