TC or reverse head ?


If you using a TC head this is how my code looks... Note my cam program at the moment doesn't support tapping, so a drill mop with custom script was needed. A few duplicates of the code I haven't had time to work out, but does work 100% every time for me. Tormach shows examples how the codes should look for both reverse and TC, check that out. This is for a 8/32 tap
