I have a Mighty Comet with a 520AM control ......
The toolchanger suddenly quit working, and all it does is to retract the Z axis to 0.0000, and then it stops ........ same thing in a program, or in MDI ...... No error message ....... it indicates that the operation is running, but nothing is happening......
I seem to remember the same thing happening once before, and I was able to get it working, but I'll be darned if I remember what I did to get it going...
Any Ideas out there??
Thanks
Dave
