wow - The little bit of playing seems to fixed the bugs (g0 exact stop, skipping collinear segments).. Also - g61 and g61.1 are different. (exact path vs exact stop) very very cool. Nice work!!
So - to explain further - G61 vs G61.1 from the manual.. The original planner ran G61 and g61.1 exactly the same. It would stop at every end point. now (this is from the manual) Snip... G61 - exact path mode. G61 visits the programmed point exactly, even though that means temporarily coming to a complete stop. G61.1 - exact stop mode. Same as G61 End snip... Now - in G61 if the points are collinear - exact path with combine them together. because - exact path doesn't have to stop at endpoints that don't make the path change direction. G61.1 is exact stop - it stops at every end point no matter what.. sam On 06/20/2014 11:52 AM, Robert Ellenberg wrote: > Many thanks to Sam for finding this!
