Z moving to below component on export of gcode

Hi

New to F360. Happy with the design etc, but can't work out why the gcode resorts to cutting from below the component! When I simulate on F360, everything looks good. When I export to .nc and check it on a simulator the gcode sends the router to below the component.

The cut is the right way up i.e the end result is correct, but the cutter starts from below the piece.

Tried numerous tests but result is always the same.

Any help very much appreciated.

Hi Seth

I'm using 'WinPC-NC / winpc-nc'

That post processor has a default setting of "reverse Z axis". I think that post was written for a machine that considered anything above the part to be a negative Z value, and anything into the part was a positive move.

If your machine isn't setup like that, change this setting:
