[Emc-users] Playing with G70/71 turning cycles..

First real try playing with turning cycles. Great work! - It took me a couple trys to get the path to do what I wanted - but not too painful. Did get linuxcnc into an infinite loop once. Other than that. I write a lot of gcode by hand - this makes lathe work really easy. create a simple

Lol - I always make sure that when I am visualizing a piece of graph paper on the machine - when I command a positive for both x and y - the tool would move up and to the right on the paper.. (and Z negative gets the tool closer to the part) sam On Mon, Apr 11, 2022 at 12:07 PM Todd Zuercher
