    Clear Plane Leaving Z Axis Limits

    The clear planes in my program do not want to co-operate today. I'm using a read point for the manual alignment, as far as I can see I did not forget to translate my Z. DCC_ORG Is a circle that takes 3 sample hits on the Z=0 surface I want. The clearplane at the end is where I'm getting the error.

    you have your clearplane established too early in your routine. Move or re-define the clearplane after you establish your alignment, and you should be set.

      I wasn't sure where to put the clearplane common till I read this and see an example in the F1 function.

      "The Pass-Through Plane defines a clearance plane that the probe moves to and then passes through to get to the next active clearance plane after a probe's TIP command. The new CLEARP definition command must immediately follow the TIP command to properly define the pass through plane. When PC-DMIS encounters the next MOVE/CLEARPLANE command, it moves to the pass through plane and remains at that offset distance until it reaches the next active clearance plane.

    A Clearp declaration will use the current alignment to set the clearance plane. Always keep this in mind when you're building alignments that could have varying Z locations, as the clearance plane will not change unless you redeclare it under the new alignment.

    Also, when building alignments, unless you're trying to accomplish something very specific, the rule of thumb is to always level, rotate, translate in that order. Not following this rule will lead to some tricky situations where your origin is off from where you think it should be.

      If you have created an alignment and the " TRIHEDRON" is still moving... you have serious issues 99% of the time.

            you can absolutely keyin a clearance plane.
            there's two commands:
            1: Definition of clearplane
            -- Type: CLEARP / (press tab, then select or keyin) Vector axis (generally ZPLUS) /(press tab) input height of clearance /(press tab, then select or keyin) Passthru Plane vector axis (if you want to pull out of a side-facing hole) /(press tab) input passthru plane clearance

            2: assignment of when to conduct the clearance move
            -- Type: MOVE /(press tab, then select or keyin) Clearplane

          I use a whole lot of cleaplanes. I use them so often that I actually have Ctrl + Spacebar set as shortcut to insert a clearplane command. If you have a shortcut set, it makes it really easy to insert a clearplane inside a feature the way MetsoMetrology suggests.

          I make it a practice to define the clearplane after every alignment no matter if it is a new alignment or I am recalling an alignment and I do it no matter if the trihedron moves or not. Spend an extra few seconds for peace of mind.

            instead of having to insert the move plane, it can auto-insert it by: see snip
