ok. Seems I am confusing people. CNC using CAD CAM program PowerMill.
My issue is.
One robot follows CDIS parameters set in tool path generation and the new robot doesn't. It puts random CDIS moves in that are much bigger.
In pic attached you can see we limit $VEL and $ACC for all Axis to give us smooth Jerk free robot movement when machining.
$APO.CDIS is set to 1mm
$ADVANCE is set to 3 points.
