This particular Yamaha Head I/O Board is a common failure. Yamaha supply an updated version which is less likely to fail. The cause of the problem that you see is due to the connectors on the flexing and damaging the inner layers of the board. The on

I have one Topaz X FNC machine with this problem. The head 2 FNC not change the nozzle. The head 4-6-8 is ok and change, but head 2 no, when he tries to change the nozzle he gives me an error message. What could be the problem?

If the nozzle gets changed properly but the machine still gives the sensor, then the FNC nozzle detection sensor needs to be adjusted. It is a set of 2 sensors on a plate on the either side of the FNC. If the nozzle is not changed successfully and ge

Hello We have notorious problem with TopazXi FNC head and bending head number one shaft. So far service can't find the root of problem. Looks like problem is related with nozzle station and head hit the station. All sensor head down, nozzle are co

Hi! Try to make "R_AXIS_ACCURACY" calibration for all of FNC heads for back camera only. I met such problem on Topaz-X. There was clearly seen offset on 0.8mm pitch components. I simply calibrated all cameras for FNC nozzles and problem disappeared.

Check optical head height sensors.

It turned out that only SF heads support "fine" mode, while FNC does not. Probably because above the FNC nozzle there is a "circle" rotating the nozzles, and in fine mode it can interfere with the reflection of the camera light - the element is lower

Hi. Heck no! First, you should find out the Yamaha equivalent of your machine, if known - that is a more common reference when sourcing parts. While we have no affiliation with the vendor other than a very positive history of sourcing a laundry list

Have you had you head splines inspected for dirt or contamination which would cause heads to stick? Make sure the your Splines are not bent; that they are clean, and last that your nozzle station is taught correctly. How often do you service you equi

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
