I have my z home as 0, on some prints when I slice wit cura engine it shows the first z move as 0.1 which is perfect for .1 layer height, but on other prints it comes up as z0.3 which is to high for first layer of 0.1. On second pc it does 0.3 on all slicers. I am sure there must be a simple sollution but I can not see it
