Vector Point Problem

[dtmtim]

I have a problem with vector points today. For some reason PC-DMIS is offsetting the hit target parameters which causes the machine to crash. The hit target parameters must match the X,Y,Z location of the point. It only happens on some points. If I manually correct it and execute it then it works until the program is closed and re-opened. Then it crashes again. It's driving me crazy. Wrote the program in 2019R2.

Do you have void detection on? That can create some weird bovine scatalogical samples....

[dtmtim]

That's what I thought as well. I have never used void detection on vector points. The button shows that it's on but it's greyed out and I can't control it.

Here is another screen shot attempt. You can see the void detection button on but greyed out.

That's what I thought as well. I have never used void detection on vector points. The button shows that it's on but it's greyed out and I can't control it.

Took a look at edit window code and there's no entry for void detection.

The only other thing that I can think is to check and see if your theo X, Y and Z's are the same as your target X, Y and Z's.

Is avoidance move turned on. I had similar problems and that was ticked as both for before and after. Changed that to none and all was well again. Not saying that this is what is causing this but maybe.

check and see if FIND NOMS ON EXECUTE is turned on (F5). It shouldn't be.

[dtmtim]

No avoidance move, No find noms on execute. All good ideas I thought the same.

That "Hit Basic" line of code is what is killing me. I can set it to the correct values but when the program is closed and opened again it goes back to the bad values or if someone F9's the point it goes back to being bad.,

F10 and check positioning accuracy.

The problem seems to be related to the CAD surfaces. If I toggle them off in CAD assembly the problem goes away. As soon as the CAD surfaces are visible the problem returns.

I'd check F5 > part/machine tab to see if any part offset has been entered there somehow, not sure if that offset affects the target value directly but it works much like you are describing

[dtmtim]

Thank you, no offsets are entered. Only about 5 of the 100 vector points are affected.

wondered that after replying, if the problem point was the first hit in the program or not. Are all the affected points in the same axis or direction? something else the affected points all share?
