    G54 PROBLEM ON 840C

    I have a 1994 HIT-15s and when I try to set the G54 with the WCS in Z it gives me a number that is exactly 1" off. Does anyone have any ideas on what i am doing wrong.

    thanks

    I first use the presetter to offset the tools and then put in the part and press the WCS softkey. Use jog to pinch a piece of paper and then press the WCS in Z softkey. It comes up one inch too long in the G54.

    Is the offset for the tool used to touch the part enabled before the touch off? Assume you determined the offset error by running the program. What does the DRO read when the tool is physically 1 inch away?

    The tool I am using is enabled and I have the Z length 0.0 So when the paper is between the tool and the stock the DRO says 10.5" and when I push the softkey WCS in Z length the machine puts 11.5" in the G54 so when the program runs the tools are an inch from the end of the part. This machine has been nothing but problems.

    thanks

    I sent an email to my local dealer for more information. When they give me an answer back I will let you know.

    I got some PDF manuals back from my local dealer. After reviewing them, I do not see an obvious place where the Z work zero setting would be effected, unless you have additionally used G58/G59 within the program which would cause and additive offset.

    I tried to attach the manuals for your review, but the upload kept failing.
