I need to do something embarrassingly simple, but cannot figure out the right/simplest way to do it, and the posts I read confused me.
So, I have Vcarved and cut a set of coasters, put epoxy resin on the carved part, which I then want to surface, flush to the coaster’s top surface:
I would like to create a surfacing toolpath that starts in the air from height H, and cuts down to H-T. I cannot zero on the coaster’s top surface (there is an irregular resin layer across the whole surface in some cases).
- I can think of setting Z reference to stock surface in CAD, making a pocket toolpath of depth H-T, zeroing on stock bottom (i.e. the spoilboard), then raising Z by H-T, and resetting Z zero there. It feels like a workaround.
- this seems like a usecase for setting Z reference to stock bottom, but I do not understand how to adjust start/end cut depth then (I am using VCarve Desktop, but could use CC) to get what I want. The preview shows a toolpath cutting a pocket below stock surface, and refuses negative Z values.
I’m sure it must be dead simple, please enlighten me
