It does take longer on a lathe without a compound. You must watch the
motion, make adjustments and watch again until you have the tool tip aligned
with the threads. The more material you need to take off the part the less
accurate your position must be to restart the cutting of the part.

Gentlemen,
I have cut multistart threads and adjusted the machine to recut threads by
adjusting the start point Z coordinate. I would think it would work very
similar in EMC2.

If you try a git master build and find that it works for you, that

It does pose one question, though. With a leadscrew you can pick up
an existing thread by engaging the nut, stopping the spindle and and

Is there an equivalent with EMC2? I am thinking you could perhaps stop

Since I'm a bit at wit's end - if anybody wants to give it a stab:
Here is a hardware-free emc2 config which shows the oscillation. It
needs hal, so I guess it wont work on emc-sim, but it doesnt touch any
hardware (simulated encoder, and stepgen outputs etc not connected).

Thanks for sending this config.
Running this config on git master (14b8248a) gives me
I've pulled a fresh copy of master and now get the same (clean) plot

There's a chance I created a snafu as I blunder down the git learning
