Note 3:
If calibrating all nozzles from Nozzle tab, it seems the vision does not work. However, if I start it for all nozzles and quickly change to the SVP tab and select allow move with nozzle down it seems to go ahead. This can be tricky to get right.

If I do each nozzle using 'calibrate current' I get more success.

The issue above with homing using the up camera still persists.

Unfortunately, I probably will not get back to it for at least a week.

It was by design, as the nozzle calibration needs to disable the z axis switches. It now switches to basic setup page before homing.

Homing now switches do down camera cleanly on cameras setup and vision processing setup pages before homing.

I depreciated calibration from the nozzles setup page entirely. As you noted, calibrating all is tricky, and not worth the effort. The easiest way to do nozzle runout calibration is on the “Setup Video Processing” page anyway. Set "Vision Algorithm" column on “Vision Parameters:” table to “Nozzle tip” for all nozzles and leave “Override Size” unchecked; then do calibration on “Setup Video Processing” page, “Special Options” window. Detailed instructions at https://liteplacer.com/nozzles-calibration/.

Thank you for your contribution! I very much appreciate it.

Newest version 25-07-2022: Fixes issues on homing from other than basic setup page. Nozzle calibration from nozzle setup page is depreciated now; use "Special Options" on "Setup Vision Processing" page. Data backups now go to dated directories.

tnx

Finally got to try out the latest beta (25072022) and haven't seen any issues so far.

Got the up camera vision recognizing 0805 Rs & Cs and also a QFN32 part.

Need to try it out some more later.

One suggestion not related to beta. It would be helpful if we could increment the up/down box for threshold in increments of 10, either by holding down the shift key or defaulting to steps of 10, with fine tuning manually.....or Could also be a check box to switch between 10 and 1 increments.

Which boxes are you referring to?

The one for setting the threshold value in the SVP tab /video processing function. It appears only when the threshold function row is highlighted.

Ah. Your suggestion makes sense.
