They happen when lines meet where the width of the feature isn’t an exact multiple of the extruder’s width and the printer has trouble filling in the void. Usually they’re fairly invisible, but when printing white on black, they stand out like a sore thumb.

I’m wondering if there’s a good simple way of avoid this problem in the slicer. The ultimate fix of course is to print a square sheet of white PLA under the white letter, but I’d rather not mess with my model because it’s quite complex already.

    There is less material than needed all over the place, look at the not bonded perimeter lines on the top corner.

    Measured the real filament diameter before printing and corrected the slicer settings to the measured diameter?

    Are the extruder steps calibrated?

    If iam to lazy to reslice, i would increase feedrate to around 106% and look at the following layers if the gaps are closed mid print.

    This can be seen at layer 2 and corrected while printing

      No and I don’t even know how to do that 🙂 The printer is the company’s Prusa XL and we’re using it as it came out of the box. I’m normally very happy with what it churns out, it’s just that small esthetic issue on a part that bears the company logo, that we intend to sell to customers.

      I’ll look into that. Thanks!
