Fuji CP6 Y-axis placement problem

Fuji CP6 Y-axis placement problem | 19 March, 2008


I am having some problems with my CP6 placement changing in the Y axis. I had to move all parts by +.12mm this morning. Then after 20 boards the placement shifted too high by about .12 mm

The IP stayed the same with the same pcb's and fid coordinates. All parts have main mark and sub mark.

This has happened on a few other differtent products lately.

I also powered down the machine.

Any ideas if its the servo amp, card or lead screw?

#1Run a Fuji gold board and see if the problem persist. Is your board clamp slipping? Fid camera tight? etc..

To see if you have a Y axis positioning problem:

1.Put the machine in mecha check 2.Go into Y-axis 3.Place a dial indicator so that the stylus is touching some area on the front of the table in the Y-axis.Zero the indicator and cycle the Y. The indicator should return to the same place every time.

If you are not familiar with mecha-check then you should call Fuji, or one of the after market Fuji folks. BE ADVISED... It can be dangerous if you do not know what you are doing.

Good luck.

Don't try the mecha check yet unless you know how. have you checked the coupling shaft of Y-axis? If it's ok, take a look at the ball screw if it looks like being scratched or something unusual. Also, observe the movement of the machine if you hear any humming on Y-axis.

Anyway, if you have complete manuals of the machine, there's a guide in mecha check operation.
