Ahhh, ok. After reading the description of G64, I am realizing that the reduction in feed rate is probably due to my acceleration limits. I have not really tuned those parameters and they are probably still very conservative. Does that make sense? A question about radius cuts. I would like to be able to command a circular cut simultaneously in XY and UV (to cut a cylinder). G01 x10 y10 u10 v10 G17 G2 x10 y10 u10 v10 i0 y2 I assume that this will cut a circle in the XY plane with a radius of 2 and start/end at x10 y10, but it seems from the description that uv will remain stationary causing me to end up with a cone, is that correct? Or is there a way to tell it to use both xy and uv for the circle? Ryan ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
