Hello,

There is a recent discussion on the forum of a similar nature. You might want to look at that. Sorry I forgot exactly where it is.
Do your rapid moves work at the correct speed?
A couple things to check.
Are the moves extremely short? Are you using G64? Do you have the feed override set at 100%. Also look at your acceleration rates if the moves are short and the acceleration is long .
