The reason I am trying to do all this is because I am going from an old CNC to a new one. The old one, I never z zeroed off the spoilboard. I always z zeroed off the top of the stock. So now I have 100 old toolpaths that I would have to change all z depths to a positive amount for cuts. Or, physically move all geometry. This would be very time consuming. I just so happened the stumble across the AXYZ post processor doing exactly what I wanted to do by simply putting the WCS toolplane at 0.7" for Z. It would be a fast and easy way to not have to edit all my toolpath cut depths. And to answer your question, I am using Absolute in linking parameters. Thanks for responding btw.

Hi everyone. I am using Mastercam X4 (old, I know). I am trying to add some features into a Generic Fanuc 3X post processor. The features I would like to add are actually from a AXYZ Generic 3X post. I know very little about editing post processors but I believe the post processor code I am looking for in the AXYZ post resides in "#Position Calculations" section. Specifically, I think it has to do with pmatrix_su, pshft_map, and pxyzcout. (all located in the specific AXYZ post) What I am trying to do: I set Z zero of my stock at the bottom corner (or spoilboard top). All my geometry is laid out on the bottom of the stock. I set the toolpath WCS tool plane to 0.7" above the toolpath geometry. This way, I don't have to physically move the geometry up to the top of stock. The issue I then have with my normal Generic Fanuc 3X post processor is that it will obviously read a depth of cut of -0.25" when I put that number in the linking parameters. With the AXYZ post processor, it will automAXYZ GENERIC 3X ROUTER.PST.txtatically output the gcode to actually cut at 0.45", though in the linking parameters, I actually have written a -0.25" depth of cut. (exactly what I want) The AXYZ post processor basically does all the math for me, and I can still use negative (-) z cut numbers in the linking parameters rather than positive numbers, which makes my life easier. Question: How can I integrate the AXYZ post processor code into the Generic Fanuc 3X post processor that works with my CNC? attached is the AXYZ post processor (in TXT file)AXYZ GENERIC 3X ROUTER.PST.txtAXYZ GENERIC 3X ROUTER.PST.txt
