Have a brand new Haas VF-6 with probing. Am running castings that I am using the work probe to touch off and set Z axis zero. Problem is that I want to remove .025" from casting and have that be my Z = 0. I can't figure out a way to have touch off with Renishaw work probe NOT be zero but be +.025 Our brute force solution was to just do a quick operation to adjust the preset G54 by summing macro variable for G54 Z value with -.025 to move the G54 work offset down .025". This caused an unanticipated problem with running the mill with "program restart" enabled. Now any time you exit and restart program it does the math operation again and lowers the G54 by .025" NOT a good thing. We can't figure out what variable the probe touch in Z is stored in so we can do the math operation on that variable and not the stored G54. Also does that variable stay fixed until the next probing function? Playing around with the part zero setting options I see nothing that allows for presetting to values other than zero. Any help appreciated!
