General Mach Discussion / Re: re : Mach turn ,tool radius index too big

Spindle speed averaging won't cause the problem as it only looks at 8 or so different rpms and then averages them
for the threading planner.
If you are trying to cut a thread and your axis velocity is not fast enough for the feed rate then the threading wizard will
warn you and not post the code. That is the reason i suggested you generate the code from the wizard.
I didn't remember if the G95 wouldn't be activated though and that may be the case.
Didn't look at the code Hood posted.......you should have around 3 to 5 x the pitch in Z travel so the axis has time to accelerate.
Would seem that with a correct rpm showing that you should get an index to start the treading.
What version of Mach are you using? ....hopefully somethng greater than V3.042.32
