Hi all
Can someone have a look at the attached photos of gcode and let me know what I'm doing wrong.
I running it on an old okuma Lb15 with OSP5000L and trying to lathe some threads ...
It stops at the G33 command
Tried lots of different things and stops at the threading code ....
Any ideas ????
Thanks for looking

7-2-1. Fixed Thread Cutting Cycle: Longitudinal (G33, G31)
[Command format]
G33 X__ Z__ { } (E__) F__ (K__)(L__)(J__)(C__)

A thread cutting cycle can be programmed in the same manner with G31 as with G33.
G33 : Fixed thread cutting cycle (longitudinal) command
G31 : Fixed thread cutting cycle command
X : Thread diameter for each thread cutting cycle
Z : Z coordinate of end point of thread
F : Thread lead (F/J if a J word is provided.)
I : Difference in radius between start and end of taper
A : Taper angle (Taper is specified by either an I or A word.)
E : Lead variation rate per lead for variable lead thread
K : Z-axis shift amount of thread cutting starting point (When no K word is specified, the
control assumes K=0.)
L : Chamfering distance (When no L word is specified, the control assumes L=one lead at
thread cutting start)
L word is effective in the thread chamfering ON (M23) mode.
J : Number of threads within a distance specified by the F word (When no J word is
specified, the control assumes J=1.)
C : Phase difference for multi-thread thread cutting (C=0 if omitted.)

Thanks for your reply, much appreciated.

This is the code im using , according to the okuma LB15 manual it should work

I have tried G31 as well but it stops at the thread Gcode ??
