I have seen this discussed before and that the software was corrected however I still have issues. For those of us with ANSI drive components we need 4 place precision to be maintained during G-Code generation. Although we have the ability to input our layer height to a 4 place decimal, when the G-code is generated, it is rounding off. My layer height is set in the factory file to .2046 mm with a first layer height of 100%. However when you open the G-Code file it has rounded off to .205mm.
; layer 1, Z = 0.2046
