Hey guys,
I need some help here.
I'm trying to cut 1 1/2 12 threads and something is wrong.

When running this code here it barely moves it would polish the bar instead of cutting threads.
G71 X 1.390 Z -8.6D0.010H0.114F0.08333M33M74


The only way I can get it close to cutting 12 TPI is set the feed times 100 Example F8.333.
Is there some parameter I have off somewhere?

Thanks Okuma gurus!
