Re: [Emc-developers] Reverse Run

well that is pretty darn neat.. couple issues I found -the first time you hit play after pausing and reversing the motion (while still paused) - no movement. -if you reverse run to the end of 20 segments (either manually or unpausing) you cannot get it move anymore. shift-f will not go forward

Re: [Emc-developers] G18 arcs bug in 2.7+

Chris figured it out. Now the plane issue I was seeing was totally my fault. When I changed planes to G18 - I just switched Y to Z. Well this makes the arcs the wrong way. Changing them to G3 fixes it. Oops. I fail at the right hand rule I guess. Sorry Rob if you started looking at that..

this program does show difference between planes.. G17 vs g18.. G18 peaks at about 320ipm vs G17 peaks at about 540ipm.. I don't see an issue with feed override. sam On 03/09/2015 08:26 AM, sam sokolik wrote: Do you have a gcode snippet that would show this? thanks sam On 3/9/2015 8:12
