Im printing the cube perpetual calendar by tonas , and noticed stuff on the layers that look foreign. is this a problem? i noticed this mid print. its basic pla black and matte white by bambu, on ams lite. just wanted to know if its a problem.
Your black looks to be overextruding due to too-much-flow, or wetness.
Try redoing your flow rate calibration, saving the result, and try again.
