Just installed an indexer on my desktop.
Was able to run a rounding tool path and everything seemed to work ok.
Tried to then run a spiraling tool path. It seemed to make the first spiral fine. When it traversed in the x axis back to start over for the second pass. It jittered and lost its place.
I slowed all of the move and jog speeds and tried it again. Same issue. Definatley seems to drive to fast. Any suggestions where to look to fix this?
