The last cut on a project (profile cut) went wrong.
No problem with the previous roughing cut, the 3D finish cut or the Vcarve cut.
When I ran the profile cut the bit plunged completely through the material and cut the profile.
Material thickness was .800
Set the z zero after bit change
Z Zero set on material surface
Profile depth of cut was set at .815
Multiple passes set for profile (6)
Tabs set at .375 length and .200 height.
Scared the **** out of me but I let the cut continue until at the start of the cut it again plunged the cutter at which time I hit the spacebar.
