LSP X1h + 2015.0 / 2015.1 = no go?

vpt.se
For anyone out there with an LSP X1h and are using 2015.0 or 2015.1:
Experienced any problems with calibrating your probes?

Example:

For the first two probes below, I have answered YES to the question if the tool has moved (only way in order to get values that matches the THEOs):

The machine can't complete a DCC calibration of the angles, only A0B0... It either touches the calibration sphere or errors out giving me the "Invalid reading of measured point".

Hexagon tech tested the calibration using 2013 MR1 which passed, ie. PC-DMIS could calibrate the angles as expected so it seems that the issue is related to 2015.0 AND 2015.1. I have tried with deleting the probe files, creating new ones, creating new tool, hit/retract values, analog probe values etc., to no avail. Needless to say, machine is not fit for use in it's current state - if used together with 2015.*

Why not downgrade? Because with our CMM programs collection, backsaving is out of the question - that's why.

Anyone else seen this?
  • Is the "invalid reading of measured point" a PCDMIS error or a controller error? What controller are you using?
  • For the first two probes below, I have answered YES to the question if the tool has moved (only way in order to get values that matches the THEOs


    Can you explain what you mean here?
  • Have you compared the probe parameters at the controller and registry settings between the two versions?
  • I have seen this "Invalid reading of a measured point" error in my programs on my Optiv, but it VERY intermittent. Running a Tesastar controller with a Metronics board with a TP20 probe. I just click continue and the program runs fine. I have not seen it while calibrating however. I have had a service technician, while up here for something else, check the probe parameters, and everything checked out. He made "note" of the intermittent problem.

    PC-DMIS gives the error message, I assume the controller tells it that it can't calculate the measured point. It's an FDC.

    Calibrating the A0B0 (and telling it that the tool has moved) gives me measured values that is close to the THEO probe values.
    Calibrating ANY angle after this (answer NO to the question that the tool has moved) will result in MEAS values pretty far off compared to the THEO's.
    Calibrating ANY angle after A0B0 AND telling that the tool has moved, will yield MEAS results close to THEO's, but I lose the relationship to A0B0.

    Have you compared the probe parameters at the controller and registry settings between the two versions?

    This is over my head. The webinterface to the controller is password-protected. The Hexagon tech has transferred the working settings from 2013 MR1 to 2015.x but it still doesn't work. Using a different computer (Hexagon techs) with 2015.x yields the same results, but works fine with 2013 MR1.

    This case is now being actively pursued by the nordic branch support, but I wanted to try all venues since we can't trust the results in it's current state.

    Sorry, I should have been clearer - are you talking about the XYZ offsets or the diameter?
  • I'm not seeing any problems and my probes cal to .00001" to .00003". Very acceptable IMO considering the environment the machine is in.

    The XYZ offsets. But not only that, it simply cannot perform an automatic calibration of any angle (except A0B0) without erroring out.

    Thanks for chiming in!
  • I should've added I am using 2015.0 SP2.

    Are you using parameter sets? What cal settings are you using? Have you performed a lower matrix?

    IF you're saying the sphere has moved then the MEAS should be exactly the same as the THEO, or should not change from the previous offsets at any rate.

    I'm assuming from looking at the results you previously qualified this probe answering 'No' to the 'Has Sphere moved' question (after defining the reference sphere position with a different (master) probe)?
