  • No Probing Within Probe Limit (but it is within!)

    Hello I'm trying to measure a part running a program that was sent to me. It was running ok but then when it went to measure one point it said it said "no probing within probe limit" but it does touch the part and it does it on the right place. Is it an error?

    right on the 'limit', increase the prehit & retract values for that hit.

      I have already done so but it keeps saying the same error.

    You can increase your "CHECK" distance. Maybe part is just barely out of the check-distance range.

      Where can I see the "check distance"?

    Is the vector correct for the hit?

      "Check" distance is under F10, Motion tab on my version of PCDMIS

        you can also type it into the routine (at the top of your routine, within the edit window).

      Ok I changed the Check distance just as louisd and hi-tech redneck said and it worked. Thanks. Can anyone explain to me what the check distance is?

        not 100% sure, but I wanna say it's a percentage before and after Theo location the machine will "Look" for a hit

        CHECK is really only useful when the Pcdmis default don't work. For example, to stop the machine from traveling as far when it misses the part, or if there is an interference issue under a hole (for find hole). I've only used it a couple times in 30 years. WITHOUT a CHECK command in the program, Pcdmis will travel TWICE as far as the prehit value past the THEO values for a touch.

      Searching check distance in the index of the help file gives a great description with very helpful graphics!

        I just want to let everyone know that i was running the incorrect program.

          check is how much further it will go past the theoretical hit to find the surface. If it does not find the part within the check distance you get the alarm you described. Call me old fashioned but I say screw pcdmis defaults and always have them in my program
