Simplify3D User Forum

I am using Simplify3d to preview gcode files created by my own custom program. However the preview view defaults to a graphical layer height of 0.2 mm which makes it look like the layers are not in contact if the print layer height is >0.2 mm.

In this case the base gcode was create in Fusion 360 with a layer height of 0.3 mm, however as you can see it renders as a 0.2 mm layer.
What do I need to add/change to my gcode file to make the layer render with the correct height?

Answer from Simplify3D

The viewer determines the bead size based off of a comment with the following format:

; tool H#.### W#.###

where the ";" is the comment character, the decimal number after the H represents the bead's height (mm), and the decimal number after the W represents the bead's width (mm).
