Tesa 300 questions

I'm not sure what gives with this thing, but it deleted the recall porition of a bunch of my alignments. Won't read a fresh dcc alignment to "find the part" before it does measurments....GGGRRRRRRRRR!!!!!!!!!!

Update,
I believe I have the alignment deal licked. It still doesn't like small arcs and radius's - location seems to move.
I'm still having problems with the laser and -z- axis. I would love to be able to use iterative alignments, but without the laser acting properly (like actually picking up the surface) I cannot use the 3 points to "level"...

The laser on the VISIO300 is not a measurement sensor, it is a positional laser pointer, so will never do measurements. You would need to use the video auto focus to measure the Z (vision surface point features). As a rule of thumb, set the measuring time In seconds) to be double the distance (in mm).

what is the positional laser for? Does it help in detecting a edge? There for what?

It's primary purpose is positioning. As it's in line with the optics, if you are struggling to position the camera on a feature (when programming or manually aligning), you can switch the laser on (the Laser toggle button in the bottom right of the probe toolbox). You can then see the laser spot on the part, and move the stage so the spot is over the feature to be measured.

It's secondary purpose is that it can help auto focus on parts/materials where you are failing to illuminate properly with just the lamps. There is an option in the focus parameters (Laser On/Off) - which if on will switch the laser on during the video focus operation. It is still doing a video focus, not a laser focus. Having the laser can sometimes help to illumination surface texture, which will help the focus algorithm - which is looking for image sharpness.

Vision systems with TTL or WLS lasers (Optiv, Mycrona, VISIO500) will use Laser Surface Point features to make the laser do the actual measurement.

Thank you for the clarification!!!
