Read point alignment.

FAMOUSX1
Good day all,
I am attempting to start programming using a read point alignment. I am either not doing it right at all or I think the issue might be that I am using clearance cube.

any help is much appreciated.

    PNT_READ (CTRL+ALT+G, I think Slight smile ) have to have THEO values same as nominals of your CAD/drawing, so If You have model, You need to have origin 0,0,0 of CAD model in same place as your start position.
  • If you offset the alignment values by the readpoint you can select any feature on a CAD model and use that and keep all the co-ordinates the same.

    +1 correct!

    We have to have the Theos set to the CAD coords where the probe should be parked when the Operator clicks OK on the comment we put before the Readpoint.

    What is giving you issues regarding the use of read point alignments?
  • When I try place the probe inside the hole I am trying to start at, The machine either says out of tolerance or it will try to move way up.
  • in reply to FAMOUSX1
    Put a comment telling you/your operator where to put the probe. Ensure the comment says somethign along the lines of "Pressing Okay to this will engage DCC Mode".

    Turn on DCC Mode.

    Put your read point. Then align to said read point.

    Note that you still have not physically touched your part. In order to use clearance plane or cube to move around your part, you have to be PHYSICALLY aligned because a read point alignment is treated as REFERENCE ONLY by the software.

    So, do what I've laid out and then use move/point or move/increment to get around your part until you've physically established an alignment. Once a legit alignment has been made THEN turn on clearance plane or the cube, then start rockin and rollin with your program.
  • Thanks for the help Dan!
    I am going to give it another try in a bit.

    only problem I see is that when using clearance cube, it is always on.

    Maybe I can just disable the first few features to get around the part.

  • in reply to FAMOUSX1
    Exactly. Disable those first few features. Use the moves I told you to get around your part until you've established a physical origin and then turn on the cube and you'll be on your way. No problem glad to help.
  • in reply to FAMOUSX1
    Do you know about move/point or move/increment and how to properly use them?
  • in reply to FAMOUSX1
    Yup. I can move around.
    I use a lot of move/relearn when offline programming.
