Carousel Problems!

Hello all,

On a VMC20, the atc will not move forward to the spindle. I removed the top cover and observed that the slide motor will only rotate clockwise, as in retracting the slide. When I try a tool change, the motor turns clockwise and then times out. If I manually move the slide to the spindle and hit the MDI button, the slide will cycle back on it's own. I checked fuses F5, F6, F7 and F8 all are fine. I then swapped relay K5 with K6, no difference there. Tried it with both sensors in the slide arm disconnected and the motor still runs clockwise.

Where to next??

Check out relay K33.

Neal,
I swapped K33 with K5 and it still does the same thing.
