Our Dual-Turret Slant-30 with Mazatrol T4 control (YT4B) had memory battery go down, and we lost all parameters.
I used Mazak Service Bulletin 0989-002 "How to re-initialize a T2\3 Control". I had called Mazak to see if they had a service bulletin specifically for the T4 Control, but they did not find any, or at least did not call back. So the T2\3 procedure seemed to work OK.
I hand-loaded all the parameters (I have done this multiple times), verified no mis-typed entries, and then operated the control.
The problem occurs during homing. I home the Z axis, all looks good, then home the X axis. As soon as that home is completed I get "Error 102: stored stroke limit -X1". Same results if I do X axis first then Z - error msg comes up after both axes are homed. The same type error occurs (except now -X2) when homing the lower turret system.
I have cleared all stored programs, and tool data.
It seems like I am violating some software travel limit, but I have gone through what manuals I have, and could not find anything that looked close.
Anyone got any ideas?
Thanks,
Steve
