Hello! This would be my first post!
I'm a newbie at 3D printing but have been playing around with our new Makerbot Replicator Z18. When i print a 20x20x10mm cube on ANY of the default settings in "Makerbot Desktop" the X & Y size are quite accurate, but the Z size comes out to around 10.2-10.25. I've even went in and tweaked around with a few of the settings but not much change with the overall size.
My question is, What settings would I tweak to get the Z axis size closer to the actual 10mm like it is supposed to be?

With the over abundance of settings to tweak, there has to be something in there that will affect how tall the part comes out, other than changing the actual size of the model to compensate.

Thanks is advance for any advice!
