Can't reverse spindle - CNCzone.com-The Largest Machinist Community on the net!

I'm trying to cut 1-1/8- 12 left hand thread. The spindle tries to startup in the forward direction and kinda makes a strange sound. The machine goes into alarm mode and I have to cut the power off to make it restart. i make the spindle run in reverse manually just fine. This is the first time I have tried to run in reverse. It's a 6T control. Any ideas?

Post your code and the alarm that you received, this might shed a little more light on your problem.

I got it to work by commanding M03 then M05 then M04.
