I do 98% of my lathe work with ngcgui subroutines, having said that when hand programming arcs I use radius mode. JT On 6/5/2014 12:14 PM, Marius Liebenberg wrote: Would you say it is better to always work in any one of the modes? I mean Radius or Diameter? On 2014-06-05 12:33, John

I intend to do that as well. Did you check out the Gladevcp add-on that Nick did http://www.linuxcnc.org/index.php/english/forum/40-subroutines-and-ngcgui/26578-linuxcnc-features-a-kind-of-ngcgui I have it loaded but not working all the way yet but it looks to be a great tool for lathe

Ngcgui is also good for me but I like how Nick's program strings a lot of commands together with some degree of programmability on the fly. On 2014-06-06 17:14, John Thornton wrote: I gave it a curious look but ngcgui works for me so I'm reluctant to change. JT On 6/6/2014 7:36 AM, Marius

On X you can get confused if you forget what mode your in. For diameter mode it is 2 x the dowel + the diameter of the object in the chuck. For radius mode it is the diameter of the dowel + 1/2 the diameter of the object in the chuck. JT On 6/4/2014 8:08 AM, Marius Liebenberg wrote: So for
