So do I. TLM is dangerous w/o that stanza of hal code. If the motor is started, its got about 50 milliseconds to register a passing A pulse edge, so the motor is killed before it has made half a rev when the head is in neutral, or I've broken something in the drive between the motor and the spindle. Timing is fairly critical because I had to give it enough time to reverse at the bottom of a rigid tap. If it didn't shut the motor down, and its in neutral, the motor hits about 10 grand in 2 seconds or less since the pid just keeps hitting it harder and harder. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
