I was checking out the new gSender version 0.6.9 performing a pocketing operation. I used the cool new outline feature and it raised the router 0.197" traced the outline and then at the end moved the router past Z=0.000 and attempted to push the end mill to -0.197. I ran this a few more times with the router at a new higher Z=0.000 and it repeated the post outlining Z movement to -0.197. I did not see an outline settings page so I wanted to report this. I love the feature and can work around the below zero plunge, but thought you fine folks would want to know.
@whittamps the heads up on this was appreciated and helped us to find the issue you mentioned. Have you tried the outline feature on a more recent version with greater success?
