I have the exact same problem. I set my mill at the very top of the stock and the machine drags it along the stock to the milling start point, then it goes up to the retract height (after scratching the surface) and back down to the cutting height, which makes absolutely no sense! I searched high and low but could not stumble across a solution other than setting it up high enough so it wont scratch then manually setting it down once its about to start cutting. I know there is a fairly simple setting that needs to be tweaked but I just cant find it.&nbsp;</P><P>I'm using GRBL post processor from OpenBuilds on a home built cnc machine.</P><P>&nbsp;</P><P>any and all help would be appreciated.&nbsp;</P><P>&nbsp;</P><P>thank you.</P> Wed, 29 Nov 2017 15:29:42 GMT g.awada 2017-11-29T15:29:42Z
