G76 giving an odd result
Posted: Thu 13 Jul , 2006 3:38 am
I am having trouble programing my NovaTurn for the G76 canned cycle. I don't know what it should look like on this machine so maybe you could help. Here is an example thread.

the behaviour the machine exhibits is that it starts the thread then just repeats the pass over and over again without end. It should do it about eight times.
Any ideas about how I am mis-programing this? I am at the latest releases of VR turning and the controller firmware.
Thanks in advance!
