A very small percentage of AMAYA machines exhibit thread feeder “clicking” during color change. This clicking occurs when the home position of the feeder drive gear is not aligned correctly with the feed gears in the thread feeder assembly. The user can adjust the home position of the feeder drive gear to alleviate this in machines that exhibit the problem.
To adjust the feeder home position, do the following:
Select the Head Timing tab in the Maintenance dialog.
Move the needle case to needle 1 by pressing the and keys.
Sight down the thread feeder gears from the right side of the color change mechanism. From here, you can see how the feeder gears mesh.
Adjust the alignment by pressing the and keys (positive direction) or the and keys (negative direction). The machine will beep to confirm. After each command, the feeder mechanism will re-home using the new value.
Once the alignment looks good, verify it by manually color changing from needles 1-16 several times. If clicking is still observed, go back to step 5.
Notes:
The range of adjustment is +/- 7.
These settings (enable and the adjustment value) are stored permanently in the AMAYA control board. If you change control boards, you will have to readjust the feeder home or you can write down the adjustment value from the old board and enter it into the new board using AOS.
This feature is available in RSA versions 4.02 and later (XT) and in RSA versions 20.36 and later (Conventional). If you switch to an older version of RSA file, the AMAYA will revert back to the old way of homing the thread feeder, but the settings will NOT be erased.
