Hi Tom,
Any progress with the threading?
I tried to run the C programme a couple of days ago, after having changed it to do a righthand thread and altered the pitch and overall length of cut but I had no success.
It may be that I missed something in the sequence but I couldn't see what it may have been.
If you can integrate it Mach3 that will be a major step ahead.

I will try the threading again, with the C prog. and let you know.

Hi Ross,
 
I think we have found the necessary hooks from Mach3 that we need.  Basically there is a flag "WaitingForTrigger" that informs the Plugin from a G32 that we should do a synchronized motion.  We also need to clear the flag for Mach3 to continue and also not complain about "No Spindle Feedback".  Also a "Threading" flag should be set during the process.  Mach3 then generates a time dependent motion performed at max acceleration calculated assuming the last measured true spindle speed would be constant throughout the motion.  We then need to adjust the motion based on actual spindle position throughout the motion as it is executed.
 
So the short answer is that we should have something soon that operates directly from Mach3.  Is your lathe available for testing?
 
Thanks
TK

It most certainly is Tom.
Just let me know when you want to do it and I'll be available.
