makes sense. large arcs or full circles running the same speed probably isn't a big deal. arcspiral and spiral running the same would probably be better (speeding up short arc segment with different axis velocites) if possible. (short arc style gcode)
I might be able to run the latest experimental3 on a real machine today thanks again sam On 03/08/2014 11:50 AM, Robert Ellenberg wrote: > It would be really nice to have consistent behavior between lines and arcs > that way, though I think the limitation is not in the blend arcs > themselves.
