HELP error calculation deflection matrix

Error calculation deflection matrix after completing calibration for some tips. what is it?
  • Is it possible to have that error msg. because of the improper removing and installing the probe module?

    With Leitz LSP, you need to click on two buttons on the joystic before removing the tip, then to install, click them again, install the tip then click on the enable probe.

    If, one of the steps is missed could it engage the error message?
  • Are you getting this error during a qualification? That's the only time I've ever seen it.

    Check your stylus length (I believe 110mm or 115mm is max spec for the X1s) and your OptionProbe settings.

    Which two buttons are you referring to here? Is this on the standard, Hexagon issue, single stick jog box? All I have ever done is to press the disable button, remove the stylus, put the new one on, and reneable. This is with a X1-M with Tesa wrist.

    I seem to remember having seen your error message once. I believe that I homed the machine, ran the lower matrix cal, replaced my stylus in case of a loose or damaged ruby, and then recalibrated. I've never seen the error again. It might also be a good idea to verify that the kinematic coupling is properly engaged. I have seen a few instances of puck being on but being slightly shifted and not fully engaged. This was likely caused by a bad probe rack alignment in our case.
  • Yes that jog box. Its Slow and disable button, then its recommended to click on probe enable on and off. We have been removing the probes without pressing any buttons.

    What is lower matrix? I've been reading about the lower matrix, do I do this every time I "move the location of the sphere?"

    Also, after performing a matrix calibration, then restarting the machine, then Calibrate tip 1 as if the " calib. sphere has been moved?"
  • As I understand it, the lower matrix is the fundamental matrix that establishes the location and orientation of the mount point. The individual probe angle offsets are related to this matrix, which is in turn related to the machine home position.

    You should only need to do it if the machine has been crashed or significantly altered in some way. Definitely not something that needs to be done every time you calibrate. I believe the tech will do it at each annual machine calibration and, if nothing is wrong, you shouldn't need to do it again.

    It is part of the whole calibration system so if something is not working in the calibration process it doesn't hurt to run it again. It will instruct you to use the most rigid stylus that you have. We use the 100mm puck, which is the shortest our probe can use, with a 5mm x 21mm ruby stylus. You can see the current values for the lower matrix in the settings editor. I always go in there and copy them out to a text file so I can compare the new numbers.

    I do the procedure like this:

    1) Calibrate A0B0 on the master stylus that I am going to use. Answer "Yes" to has the sphere moved.
    2) run the lower matrix (all you have to do is check the box for it in the measure dialoge and click measure). If you have multiple angles defined for the stylus you must only have your A0B0 angle selected or it will give you an error. Answer "No" to has the sphere moved.
    3) Follow the prompts
    4) When it displays the new data check it against the old numbers to verify that nothing is crazy different. The numbers will be different but shouldn't be wildly different.
    5) Requalify my master tip answering "Yes" to has the sphere moved.
    6) Qualify my other tips as usual answering "No" to has the sphere moved.
  • After performing the lower matrix on one probe, then performing a standard calibration on the same probe, I don't have that error, but as soon as I close the Utility window I get a NEW message, PROGRAM IS USING A PROBE FILE that is calibrated on different dates", why is that? see attached.

    after the lower matrix cal, it asks to shut down the program window, so do you shut id down before calibrating tips, or you calibrate tips, then shut it down
  • When you run the lower matrix you must requalify everything. This includes requalifying A0B0 and telling it "Yes" to has the sphere moved. As far as the machine is concerned, everything is out of date the second the new lower matrix numbers are sent to the control.
  • I follow the prompts exactly as they appear. Keep in mind that I am using a more recent version of the software than your re so you might see different prompts. I have never used 2010 so can't comment on exactly what you will see there.

    DaSolo, after performing lover matrix, it first shows the values .1223 etc.., then it tell you that in need a new machine start, you press OK, then it promts to Shut down window... that is how it happens
