  • Fixed star probe on probe file

    Hi everybody.
    Today, I just buy a M2 Fixed Star probe. I tried to build it. But no luck.
    When I set the 5way probe, then I don't know which size to insert in Tip#1,2,3,4,5. Anyone give me the instruction to create this. I am really appreciate.
    Thanks

    Tip#1: this is the verticle bit below the knuckle joint. Standard size for Rennishaw A-5000-3626 is ø2mm ball by 18mm length.

    So in setting up the probe file, tip#1 is: 2BY18MMSTAR (this is the second probe on my pull down list)

    Tip#2-5: these depend on the size star tip's working dia. For the above A-5000-3626 this would be ø30mm.

    Tips#2-5 therefore: TIPSTAR2BY30 (for all four)

    You may need to adjust if you have the smaller star probe, or an oddball size- in which case you're going to need much more detailed help than I can do.

      Thanks for quick respond. It works great. Would you tell me next steps how to set up for caribration for Star probe ? . I have read alots post in this forum, but I still get confused.
      I just caribrated Tip#1 A0B0, Tip#2 A0B0,Tip#3 A0B0.Tip#4 A0B0. Tip#5 hit in the shank of Tool Sphere.
      Thanks

        Try calibrating just #5, you might need to do it a few times. Also, increase your prehit retract. Both of those should help.

        See this thread too.

        When in doubt, post code. A second set of eyes might see something you missed.

          Tip#5 is the one pointing toward front. Try to align it as much as posible to avoid crashes against tool.

            Hi.
            Tip#5 is ok, only tip#4 was hit in the shank of tool sphere. I think because it is too short, my two tool spheres is 45 deg. May be I will caribrate tip#5 at lower tool sphere. Any suggesion ?
            Thanks again

              I've always calibrated off a single sphere, generally without problems- so I don't quite understand the dual artifact proceedures.

              If how it works here helps there; First time run qualification in either manual or manual+DCC. Keep in mind which probe tip is which as the only clue otherwise is the offset shown in the program window. After the probe is qualified, immediately re-run in DCC+DCC to do it better.

              Since you're shanking, double check the shank vectors in the tool menu. Changing these to match 45° (in the right vectors) might run the qualification program right for you. You could try changing the Calibration Mode to an angle greater than zero (default) which will measure further up from the centerline of the sphere.

              Good luck.
