Set up question

Can someone explain the advantages and disadvantages of referencing the Z off the material surface and also off the machine bed? I’m still waiting for my OF but am trying to do my best learning Vetric. Thanks for your help!

My approach has been to zero off the wasteboard when I want to cut all the way through the material and to zero off the material surface when I want to v carve or cut pockets into the material that are relative depth to the material top surface. This approach removes issues with variable material thickness from a repeatable process where you will use the same program to make the same part multiple times.

There may be better ways but this works for me.


I appreciate it very much.

I generally reference off the material if I am not cutting all the way through but I prefer to reference off the waste board if the thickness of the wood varies or may be milled away when changing bits.
