Vision Crashes When Measuring Circles

Hello!
I have several part programs that run though to completion using touch probes
I received a part that requires vision due to the crossholes (there are a lot) being generally too small

So I created the part program and was faced with many issues...
(Such as all of the numbers randomly changing by thousandths, leaving me to clean up everything with 0+0's!)

However, it is done, and I'm trying to check it, but it crashes at the first measurement.

Strangely enough, it worked before!

I have not been able to run this program all of the way through, it only crashes when it measures a crosshole.

The way the program is set up is it performs an alignment using the touch probe, then switches to the camera
The camera looks for a crosshole, and if it does not find it, it rotates 180° and tries again (where it will find it, or we made the part wrong!) Otherwise it continues as normal.

However pretty much since I added the "OnError" stuff it starts crashing at the hole.

I was able to verify that it works (the OnError) previously, and, upon this discovery, moved on to programming the rest of the part.
I needed to get the crosshole perfect or I couldn't measure the part, you see.

So it worked for a bit, but not anymore, and it keeps crashing. Strange!

I tried to measure a different hole in the same program, and had the same issue.

What's going on?

  • Im pretty sure the ring light is redundant, I really only need the top light. I just have it on because I haven't bothered to turn it off!

    I calibrate the standard way: Using the hexagon calibration plate.

    Measure the ring with vision, has moved, measure with probe, has not, measure sphere with probe, has moved, measure every other probe, has not

    The alignment takes 4 cylinders, 7 hits per ring, two rings, along the OD.
    1 point is taken on the face, and a plane of 6 points is taken inside a notch (to align upright)

    I level Y+ to the cylinder, rotate ZPlus to the plane about YPlus, Rotate YPlus to the cylinder about XPlus, Set X&Z axes to cylinder, set Y axis to face point.

    Then I measure a line on the face using vision, and I measure a line on an undercut. After that is the hole that crashes.

    If the hole is there, it crashes right away.
    If it's not, the program rotates 180° and measures the hole, and crashes right away
