If you are using Intercon, reduce the chamfer amount. See page 98 in the Lathe User's Manual.
Cheers,

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Person use G code only .

See Parameters 240 and 241 in the lathe operator's manual.
Try something between 0.2mm and 0.4mm for P240.
Optionally, change P242 to 60 degrees, and include a chamfer out of the thread at a 45 degree angle (see Parameter 49, and/or the 'P' value on the first line of a 2-line G76 cycle).

See G92, on page 183 of the v4.20 lathe operator's manual.
G92 uses Parameter 49, just like G76 does.
Set Parameter 49 = 1.0 for a one-turn chamfer out at the end of the thread.
