Does anyone have any info. on an "E869" error code on a Phillips Topaz X SMT machine. Error screen shows "Nozzle down limit sensor is off in A-table YV100X:N2323 YV100XT:n2223 Please check sensor and remove to the cause of this sensor being off.

Do you have a service manual? There is a description of how to check and CALIBRATE the nozzle sensors (section "Placement Head").

My recollection is fuzzy, but don't the heads go down first, then the nozzle? If that's true, did you fire the heads only or both the heads and the nozzles?

The heads attach to the nozzles, or vise versa, so both. At least that's what it seems to look like. Still having issues keeping the R-axis sensor in calibration this makes third day in a row of re calibrating them.

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!

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

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

R axis is the rotation of the heads. 180 degrees and -180. The sensors tell the machine when the heads are switched correctly on the flying nozzles and the correct rotation. also i think they involve the clutch as well. After i make an adjustment to
