CMM crashes on probe changer lids

Hello to you all,

I've recently installed the HR-MP 6 port probe changer on one of our CMMs. It was calibrated and successfully changed probes without issue. However, when I close the lids, instead of pushing the covers over when picking up a probe, it moves over slightly above the lid then crashes on top. I've tried playing with the (before and after pick-up distances) and (edit the probe data) to try and "force" the CMM to slide the lids over before picking up a probe. I would assume the probe changer should operate with the lids closed but for now I'm leaving them open. Is there anything I need to change to make this work with the lids closed?


  • We are having the same issue here with what looks to be the same probe rack. Iv reached out to Hexagon support. They had me delete the probe rack file and redo everything. It worked for a couple days and then did what we are seeing here. We leave the lid open and it picks up and drops off the probes fine. We tried moving the z port height but it doesn't work for whatever reason. The only port that has this problem on our end is port 1.

    Good Luck
  • Had a similar issue with whatever Hexagon calls their scanning probe setup. One day it just started crashing. Recalibrate, and it still crashes. Found the Z height for the pockets to be out the radius of the probe used to calibrate. Lowered the z position for all the pockets manually. Didn't have a problem for the remainder of my time there.
  • I've thought about opening a Hexagon support case for this issue, but for now, I just removed the sliding doors lol. I did verify the probe build and probe changer calibration procedure, so it looks like we are just dealing with a glitch.
