1992 Fadal CNC88. I was machining a small nest yesterday when I noticed the machine would move a little ways, stop, and continue on. It is not related to a single axis nor is it distance related it is a timing thing. When it would rapid it would go about 4 times as far and stop, and then continue on. I was machining in X and rapiding in Z when I noticed it. It didn't start until I had been maching for probably 25 -30 minutes so I'm guessing something is getting warm. Any thoughts?
FYI: I was doing a DNC but this was happening on an 8", single line, linear move it would stop 4 - 5 times. Of course the rapid in Z was to a tool change position, around 18", it only stopped once.
Thanks,
Don
