I will try and explain how I work. Z Zero is always the end of the stock and any material being removed in Z is towards the chuck, so negative. I put the stock in the chuck maybe leaving 10mm extra longer than the part, so say I was making a part that was 200mm long I would have 210mm sticking out the chuck. I would then call the tool I use for facing and move it to the end of the stock and enter 0.2mm into the Z DRO, then my first cut in the code would be a facing cut, it will move to Z Zero and face off, it will remove approx 0.2mm from my stock.
Now if the next part is 30mm long I will place that in the chuck with maybe 40mm sticking out and do the same, move Z to face of stock, enter 0.2mm into the Z DRO and again when I start the code it will face off the part.
Its kind of hard to explain, would be simple if I could take a vid of tool setup and how I work, maybe when I get the wee lathe up and running fully I can, big lathe is just too big to be able to set up a camera for that.
