'm frustrated
I wonder if I have forgotten any setting in the toolpath
when I have marked what is being milled
And starts,
the cutter goes up from the zero position to the workpiece
But does not go downto the pattern , but start working in the air above the workpiece
I’ve tried another thinner bit before I started,
And that was fine
Then the bits went down to the material and milled.
Sorry if I spelled something wrong here
after all I´m Swede
