I'm trying to visualize how that machine is laid out. Do they all rotate together, on a belt, so that there's only one sensor for the theta (R) home position?

They all rotate on the same belt but, 2 per head on heads 2, 4, 6, and 8. Placed on the front and back. Held by a bracket with 2 screws. But no matter how tight I set the screws upon adjustment they still get out of whack.

Can you take a picture of the front and back sensors? That might help me understand the situation. I wish I still had the visual images stored from 11 years ago but that ship has sailed!

The reason I asked about using X-Y data (originated from the pcb files) is that if you bombsite the locations with the camera and program or adjust them individually, you run the risk of having to do it over and over when fiducials change, your fixtu

Yes we do. I've done the R-axis sensor calibration multiple times in the past few weeks due to FNC Nozzle sensor errors, as well as R-axis errors. Do you suggest i go through the entire process of the Head Assembly Calibration? From section 15-1 thru

I don't see any attachments.....? Are the fiducials consistently well finished (perfectly round, shiny without splotches or other imperfections), or do they vary in quality? When you do a fid offset, is the correction consistent or do you get varie

We have several issues with components placing properly onto designated leads without having to offset our boards fiducials before population. For several of our boards, we cannot set our fiducials "dead center" but rather offset them in various dir

I'd be looking at the safety circuit as a whole. Grab a multimeter and make sure you get a full closed loop back to the safety relay, and see if the safety relay itself didn't go bad.

I don't know if it's the same in the XII series, but in the X series the emergency signal also passes through the electronics board on the head, cards in the computer, etc. - through ALL elements of the machine.

We executed that in IO screen all heads went down, N2323 sensor remained 0. And we cannot find N2223 sensor in the I/O screen. So now we are unsure of the issue but we are searching our manual in the "Placement Head" section hoping to come out with a
