Cura 15.06.02 shows incorrect number of layers

[zews 1]

My object is 92.8 mm tall. I want to print with .1 mm layers.

Cura 15.06.02 shows 926 layers. This is wrong.

Cura 15.02.1 shows the correct number of layers as 928

Why is this so? What is going on?

Please post issues about Cura on the github issue tracker. Its okay to double post them if you want to discuss this with people (It's a good way to get quick responses) but it's impossible for us to keep track of issues on the forum.

I seen this error on older cura versions. Have you tried to load the generated gcode to see if the layer it's being 'made' but doesn't show on the preview?

First layer 0.3mm: 92.8 - 0.3 = 92.5mm

Following layers: 92.5 / 0.1 = 925

926 layers in total

Thank you Robert, that explains it. The reason my Cura 15.02.1 showed 928 layers was that I had the Initial layer thickness set to .15 mm. In Cura 15.06.02 I had not yet checked Initial Layer Thickness in Preferences > Machine > Quality, so the layer thickness was set to the default of .3 mm.
