Error message

[John Kugler]

I had to build a probe from scratch with a little help from Tech Support and some nice gentlemen from Germany. It calibrated just fine, but when it was done I got an error message that said "Unable to calculate deflection matrix" for each of the four probes in my knuckle. I clicked OK, and it seems to be OK but it does not retract after taking a DCC vector point. It goes in, takes the point at then sits there.

Not sure about this one, I'll take all the help I can.
Thanks.

Are you sure your knuckles aren't dragging on the ground? SORRY!

Well, as a last resort, you could try measuring the tips in MANUAL mode. I have found that this will sometimes 'correct' vectors that it is having problems with. One thing, you WILL need to calibrate a 'good' probe setup (build up) and tell it the tool is in a NEW position, then calibrate the good build-up (one you don't have problems with), then change to the problem probe, then measure them all in manual mode after telling it the tool has NOT moved.

Well, I hope you did make sure the retract value had not somehow become "0.000". You say 4 tips on a knuckle. Do you mean a star? Or do you mean 1 knuckle at 4 different index positions? I do not know anything about the matrix error. Did you try calibrating it again?

I was told by someone that you have to qualify each knuckle angle by itself, not as a group

I have 2 cents.
Upon recieving a "Matrix Error" we increase the amount of hits the probe takes on the calibration artifact - this usually takes care of the problem, but not always. If not, we play with the start and end angle.
As a last resort, we do a "Lower Level Matrix Calibration" and this, my friend, always takes care of the problem.
Hope it works for you.

When I recieve this error I forget, is it the red pill I need to take........
