Foam Cutter GUI shows not existent Z-axis

Hi
I have the foam cutter working really well and have posted several videos on YouTube which are quite popular.
But on the display it shows an Z-axis at 38.1mm which doesn't exist in the configuration. Doesn't affect the cutting but just confuses some of my YouTube subscribers.
I've had a look a foam.ngc but that doesn't seem to have anything to do with it.
Any ideas ?

I have the foam option set in the ini

it is the just display coordinate system
you cdan get rid of this by VIEW show offsets and cordinate
or in the AXIS.tcl do show cordinate system off

there is a Airfoil python addon for linuxcnc that puts out NACa profiles

Thanks yes that helps. The airfoil generator I have seen before and is quite interesting.

you can modifi this Z Axis distence to get a good preView
(AXIS,XY_Z_POS,5)
(AXIS,UV_Z_POS,30)

Thanks for taking the time to look at this. I've seen this in the foam.ngc file is this where I change it ?
