Could you post your pattern and any vit and I can take a look at it?
Yeah… I know I addressed this before, can’t recall if it was something I fixed and was justing waiting to push the changes? Off the top of my head I do seem to recall this might be one of those fuzzy math things, where with the floating point math you can’t rely on 2 values exactly being equal, so the 1mm might be the tolerance when comparing 2 points.
