Do you change your zero position after a facing operation?

[jimmyfos]

Do I need to set my zero after every job that has multiple tasks? Does the height of the zero change when the prior operation was a "facing" operation... since the stock of wood will be lower after the cut? or do I need to save the X,Y,Z coordinates and input the same ones manually every time before the next job operation.

I'm using a Shapeoko XXL Machine for Milling and I change the Tools Manually between operations. 

Thanks in advance.

After each job, or after each operation?

If you're running a family of parts and they are all the same exact size stock and finished dimensions, no one does not need to reset the zero each time. Let's say you've got 6 different style blocks to machine, and the only difference is some hole sizes or locations, but otherwise, the parts are all the same. One would just place their stock correctly, set up some kind of stop to aid in correct locating in their vise, establish their work offsets and run the parts.

Now, if you're talking about between operations, the answer is "no". Your Setup (in Fusion) has all the intelligence it needs to allow each operation to proceed according to the setup definition. It's incumbent upon you, the programmer, to ensure that your Height definitions for each toolpath are set correctly

I appreciate the reply. so just to give you an easy example. I have 2 operations. 

1. Face

2. 3d Adaptive 

block of wood is 4 inches height

Facing operating takes off 1" inch

for the 3d Adaptive operation... Do I set the zero on the Z axis at 4 inches height again or do I take it down to 3 inches for the "new height" of the wood? Hope this makes sense. thanks.

If you set your WCS to the top of the stock, and you've defined the top of the stock as being 1" above your finished part, then no changes need to happen at the machine. Establish your WCS and run the job

Thanks so much!!!
