G92 fanuc multi-thread error

[MoSayed]

Hello,
I'm trying to do 4 start thread with g92 cycle
Control is oi-tf plus
I'm using Q method to shift start angle cause application requires to start all starts from same z value
But there is no shifting happens all cyclies start for same starting angle ignoring (Q0,Q90000,Q180000,Q270000)
Work piece dia is 35mm

Code sample.
G99;
T0606;
G97S100 M03 P1;
G00 x36;
Z-2;
G92X35Z-7F9Q0;
X34.7;
X34.4;
X34.1;
G1 Z-2F0.05;
G92X35Z-7F9Q90000;
X34.7;
X34.4;
X34.1;
G1 Z-2F0.05;
.........

Where is the mistake in the code?

Have you used a G92 with your machine before?? not all controls can use the G92, and you have to use a G76 one thread at a time.

Yes i usually use G92 cycle but in standard single start threads and it works perfectly

The X axis has to be different start point for each thread start position Here is a chart from Harvey tool but does not do a 4 start but the same applies no matter how many starts you are doing

Sorry said it had to change in the X axis and it has to change in the Z axis
