Need help with mori sl-25 thread cutting

[Kp Carmichael]

Need to know how to change thread chamfer at end of thread. Off or On.
Control is MF-T4 OTC Fanuc.

M23 Chamfering ON
M24 Chamfering OFF
Only valid in G92 and G76 threading blocks.
Even when Off you will experience more or less chamfer depending on your servo tuning.

The M24 or M23 have no effect on the thread end finishing. We are using
G92. The end finishing is on right now and I am having trouble in a narrow OD thread relief. What code would I use to turn chamfer off in G76?

Strangely enough, the 0T-C Operator's Manual says it's controlled by parameter 5130 (which doesn't appear in the Parameter Manual). The Parameter Manual says it's parameter 109.

In a G76 cycle, chamfering is specified as part of the P word in the first G76 block.

will try th G76 option. Kp

[Kp Carmichael]

perameter 109 set to 0 under G92 canceled chamfer out.
Thanks to my good neighbor
