Sometime LCAM generates quite efficient G code when processing a polyline (Only a single Z movement at the start/end of the polyline- the Polyline is treated as a single chain.)
Other times the G code generated is very inefficient, The Z axis goes up and down like a Yo-yo back to the release plane between every component part of the polyline, and the polyline is treated as multiple ( often tens of) separate chains.
As in each cast the polyline consists only of arcs and straight line segments, what then is the difference that triggers the different behaviour by LCAM?
Is there anyway of ensuring LCAM treats a polyline as a single chain? is it a function of the complexity of the polyline?
