Whats involved in switching to a different probe head?

We bought a used Sheffield D28 that has a Tesastar-M probe head. We mostly use star probes, so dont really need a rotating head. And I've heard that this model head can be a problem... thinking of switching to a PH6 or at least getting a used one to have as a backup if the Tesastar conks out. But I dont know whats involved in swapping out different probe heads... Any info about this would be appreciated.

  • I guess i will have to replace it after all.

    Sounds like it was abused.
    I talked to our Service Manager, replacing it with a Renishaw wrist is a complex undertaking. Your call...



    Just curious as to how you are calibrating that L-probe with it pointing at Z+? Where is the shank of the sphere?

    You have to create a new tool definition: a version of your qual sphere with a horizontal vector, then mount the sphere horizontally to match. Then locate it with your master probe by saying "Yes Moved DCC hit", then calibrate the up-facing tip angle of the L-star by saying "No not moved."




    two questions - can you define how long a long extension bar is, and does the line about long extension bars apply to the SM-80?

    200mm bars kill wrists of all brands, over time.
    Some wrists last longer than others. Tesa models usually don't fare well for longevity under load.
