250MY Crashed Y Axis is Now Off .150"
Local guy doing some work for me had a crash on his 250MY
Needless to say it wasn't a good crash
I'm not really all that up on the how and why it works, but everything is where it's suppose
to be but the Y axis is now .150" off, the turret did not get loosened or bent.
When you indicate off the chuck to a round tool hanging out of a tool holder and get it at zero it shows
that the Y axis is now off .150"
I know that there are codes that you enter after you power it back up to reset the encoder which he had to do one time on a older QT18 he has, but it was a guessing game to get it back in and it's still off a little bit but useable.
He explained to me that when you move the Y axis that it also moves the X axis as well and he doesn't know the proper way you reset it because the X and Y both have to be changed at the same time to make it come out right.
He's looking to fix it himself If it can be done and rely on Mazak service as a last resort.
Any ideas ?

Not Looking Good
52 reads and no replies, I'm guessing this is outside most owners and operators knowledge.
I just did this at a customers awhile ago and was trying to remember how it went.
It seemed like I detached X from Y via mcode so that Y axis moves alone, then aligned the turret in X axis until I found centerline and then grid shifted Y axis to get Y axis correct.
I even asked the guy at the customers, was there today if he remembered and he said that is how I did it. Sheesh !
Something else to always keep in mind, in the protected arear of the memory is a small program that runs everytime you index in auto mode. Make sure you dont delete it or let a service guy delete it becuase it wont run without it.
If you have any trouble with this maybe i can help you out, get in touch

While yhe endoder might be off it was discovered that when it crashed that it bent the guide pins.
So the machine has been taken apart to replace the pins, and then see what happens.
