Slic3r/Prusa Control Z model offset

Hi Guys,

I am currently setting up Slic3r PE for a customer and was wondering if there are some equivalent settings to the Gcode Z-offset in Slic3r or Prusa Control. It's been a number of years since I used Slic3r and I thought I remembered it being present.

The setting I am looking for moves the model in the z-direction and can be used to create a flat base on complicated models (see S3d z offset.PNG)



I know there is a cut option in Slic3r PE but as the models, we are using are complicated this crashes every time.

I can see that there are translation sliders in Slic3r and Prusa control but it does not allow me to adjust them or says warning the model is out of the build area




Any help would be greatly appreciated

Kevin
