Use the options in the Z Slices area to specify the values which will be used to rough machine the composite relief.
- Start / Surface Z — Enter a value to set the position of the first Z pass.
- Material Allowance — Enter a value to add or remove extra material from the surface of the composite relief. This allowance sets the distance between the surface of the composite relief and the cutting tool.
- Last Slice Z — Enter a value to set the position of the final Z pass.
- Slice Order — Choose whether to cut from the top down, or from the bottom up. Some lasers give you a more polished finish if you machine from the base of the composite relief upwards.
