Problems threading small holes 1/8-27 npt

Todd (1) from Chicago -

the threading bar is .310 and fits into bore. But after 1st pass tool backs off to .150 and crashes part. I'm running a Mazak Matrix Nexus, I changed parameter TC41, but tool still goes to .150 before it goes to the 100 (.01) escape set in TC41. Can anyone tell me what I'm doiing wrong?

Try setting parameters F 116 and F 119 to 250 (factory setting should be 8000).
This worked for me
