I was wondering if anyone might help me out with an issue I had today and maybe clear up any misunderstandings with the Z shift function in the Link's code output.
Tried to run a brad point bit for an 1/8" pilot hole as my first operation. Tool was number 14, set up as a drill operation only, and the maximum depth was .78". My Link settings are set up to run drilling operations first.
My machine only has a single spindle and tool rpm is 3k.
Generated the output from the TWD file and proceeded to run file. Machine called up Tool 14 first and zeroed out on my remote pad which zeros the bit to the bed.
Bit moves over to the first drill location. Drops a little then plunges the bit straight down untill it bottoms. Drilled thru material (.76" melamine) and into spoilboard.
I have done this several times in scrap.
Looking at the Link code there is all the correct information for tool #, rpm's, etc. The Z shift variable is also correct: .76" (melamine thickness).
I thought that the Link throws the Z 0 position to the top of the material by the use of the &Zshift at the beginning of the sheet's code? If so, then any Z position, following the &Zshift, that is positive will be above the material by that amount and a negative figure would be below the surface of the material by that amount?
If this is correct then would anyone have an idea why the &Zshift at the beginning of my sheet code is not being used? I've run the code in preview and it's there.
What I'm getting is the machine plunging the Brad point into my table surface .78" instead.
Did a Units reset. Did not help. Likewise with a computer reboot.
