Fixed Delta Scan and Probe Comp problem

ReenignE
I am reverse-engineering a large structure and attempting to use a manual scan with fixed delta (i want to take a point every inch) and uncompensated points. There is no CAD data in this program.

The problem is that the points being created are being compensated relative to the orientation of the probe. the comp distance is not equal to the probe radius (15mm probe). Probe comp on or off does not make a difference.

If I use a variable delta scan with probe comp off this does not happen but I will wind up with too much data.

I've searched the help(less) files for an answer but cannot find it. Does anyone know what I am missing?

This error has cost me considerably. Tha project is off-site and very difficult to measure to begin with. I need to find a solution by tomorrow.

Thanks in advance,
Joe

    There are TWO places you should make sure that PROBE COMP is turned off in the program. BEFORE any of the scans, you need a line of code that says: 
    PROBECOM/OFF

    and you also need to turn it off in the scan window.

    You should only have to turn it off in the scan window, but BELT & SUSPENDERS as they say!

    I've never had an issue with it keeping the comp active when I have done it this way.
  • Where do I add the line of code (PROBECOM/OFF), in the Edit window?

    Simply place your cursor before the first scan, at the end of the line of code preceding the start of the scan, hit enter, then type in PROBECOMP/OFF.
  • "and you also need to turn it off in the scan window."
    I'm not being given an option to turn off comp in the scan setup window.
    I tried adding line PROBECOMP/off in the command view of the edit window but it made no difference. In the point data the uncompensated position is the 2nd to last position in the line followed by T=.295 (this is equal to my probe radius).
  • I was sidetracked by another project last week and was unable to follow-up on this problem. I still need to find a solution.

    I need to scan uncompensated points.

    Here is what I know so far:

    with Probe Compensation off (probecom/off)
    Variable Delta scanning produces uncompensated points.
    Fixed Delta, Time Delta, Multi-Section, etc. are creating points compensated to the tip of the probe.

    I've attached a block of code for a Multi-section scan in case it may hold any clues as to the source of the problem.

    The help file is pretty specific that in the absense of a CAD model the points measured are uncompensated. So it appears to be a bug.

    Any help is appreciated

  • Hey Joe,

    I was wondering if you ever solved this problem?

    I am have this very same issue and I have not idea what I am doing wrong or what settings I should be using.
