Setting z on 3d project

hello all,
thank you very much for the help you have given to me thus far. I am now ready to cut my first 3d project but have yet another question:

I know I need to set my x and y but must I set my z for my 3d project ? Or will the tool paths take care of that… ?

As for a 2D project, how the origin is set in the file’s Job Setup:

will need to be matched when the zero is set relative to the stock:

you obviously misunderstood the question:

I am familiar with job set up (not a total newbie) but a newbie because im still learning.

I have designed and set my tool paths for my project which is 13W x 4.750H x 1.5 thick as I know I need to find my x and y zero but do I need to find my (z zero) before beginning the 3d cut ?

Why would setting up for a 3D file be different than setting up for a 2.5D?

I never said it would be different

Then why will you not accept the statement and documentation which indicates that it should be the same?

You always have to set Z zero. You set your material thickness but the Shapeoko does not know the spoilboard height. Some people have just the stock spoilboard and others have supplemental spoilboards. So you always have to set Z zero according to the job setup of top of material or bottom of material. However over power cycles the X Y and Z are remembered so if you are doing the same job over and over with the same material height you dont need to set X Y or Z but most people are doing different jobs on every session of use. If you make yourself an L bracket and always put your material there the X and Y are remembered. If you use bottom of stock that is also remembered. But if the stock thickness changes for top of material than you have to set the Z zero every time. Personally I almost always use bottom of material (Spoilboard) so I dont have to set Z zero because it is already set. In the last version of CM the X Y and Z are sort of remembered but only after the bit goes to the BitSetter. Not sure why they made that change but you can cause a BitSetter trip by doing a change tool and just leave the tool you already have installed and the machine will move over to the BitSetter and measure your tool and the last time it was zeroed is renewed/remembered.

thank you very much, very informative I really appreciate your help thank you very much…
