Need help setting parameters for printing a vase on a FF Creator Pro

I am very new to 3d printing and would like some help in understanding how to set the parameters in ReplicatorG to print a twisted vase from Thingiverse (http://www.thingiverse.com/thing:18672). The printer is a FF Creator Pro.

The Thingiverse item instructions say to use these settings:

• 3 bottom layers
• No fill (obviously)
• 1 extra shell (making 2 shells on wall)
• Layer height 0,3 (to save print time)
• Remove the top 3 layers by hand (after gcode was generated)

I am having trouble understanding exactly what changes to make and where to make them. I know that when I generate the G-Code I can set the "Object Infill" to 0%, and I assume that is where I would set the "Number of shells" to 2. (But not sure if this is setting the shells on the wall or not.)

So my questions are:

- Where/how do I set the "bottom layers" to be 3?

- Where/how do I set the Layer Height to be '0,3'? (My popup to generate g-code says the Layer Height defaults to .27 mm. Is the comma in the instructions a typo and it really means .3 mm?)

- What exactly do I remove from the g-code to remove the top 3 layers?

I really appreciate it if someone could give me some explicit instructions on how to set these.

Thank,
BHFG

What type of slicer software are you using? I use Repetier-Host with slic3r as slicer software, if you use slic3r too, I think I can help you.
