Hi,
I have a 1994 vintage VF-3 that has started making some strange z axis moves. Example: when doing multiple drill or tap locations with say, a .100" R value, the spindle will rise anywhere from a...

Thanks for the reply.
I am back in business...sort of.

OK; I figured out what the scenario is. The pin pops in under air pressure to lock the spindle. It pops out and actuates the switch to let the machine know it's out.
The pin is slightly tapered at...

Well there's no chips on the switch.
I suspect it is just on it's way out . Every once in awhile the Z wouldn't home out on start up. So I'd crawl up there and spray it with carb cleaner, push the...

Mike,
They always say necessity is the mother of invention, and desperation is the father !!!
I figured if I modified the setting a fraction at a time, it wouldn't get things too far out of whack....

OK; I think I got it.
Rummaging through the HAAS handbook, I found the listing of parameters and there was a setting number for the spindle height. I used the formula to arrive at a higher setting,...

I did an experiment: I removed the spring loaded clip assembly from the #1 tool position, then activated the ATC FWD command.
Changer came in and acted like it was supposed to.
Now I can see that...

Mike,
The shuttle cover is opening fine; but the inner section of the actual tool holding clip is contacting the edge of the spindle housing.
You have me thinking that perhaps the spindle is...
