'98 Mazak QT20, T plus control.
This machine has been drop dead reliable until yesterday. I get a call over and one of my guys tells me the lathe won't move in X. Hmmm, hes learning 3 totally different machines at once, so its usually wrong mode or something. Nope, tooleye extended and the machine will only jog Z+.
Presetter won't retract, power down/power up. Everything works, anyways, when you hit the presetter(any direction), the LED on top goes off and it registers the offset, but when you move off the presetter, the LED doesn't come back on, and it will only allow you to jog in one axis away from the presetter. Power down/power up, LED comes back on and everything works.
So the machine doens't realize that there is no tool contacting the presetter, the buttons are popping back out and the offsets are registering just as accurately as they always have.
I don't think the presetter is the problem, though I've been wrong many many times. Relay? busted wire? Fuse? I haven't pulled out any schematics and I called Mazak on their lunch break and never got a call back. Its not that big of an inconvenience right now, but when the machine goes back to running 3 or 4 different jobs a day its going to be frustrating.
