How can I tell how deep my V-Carving is?
After the software has calculated a toolpath, it displays a summary of the toolpath data on the 'background' of the Toolpath tab. This is only visible when no other form is open on the Toolpath tab, so you may have to close the Preview form to see it.
As you click on different toolpaths names in the Toolpath List this information will be updated for the highlighted Toolpath. Find the Min. Z line and it will tell you the deepest that toolpath will cut.
As well as showing the Min. Z value for the selected toolpath, this information also includes feed rates, tool information and estimated machining time.
