Gentlefolk,
Thanks for all the comments and suggestions.
Back looking at the basics. How do I know the motor is 50 steps/rev???
The motor is an Epson EM-257 which I have not been able to find much
about on the Internet.
I held the shaft of the motor and rotated it carefully. 50 "steps"

Splitting hairs, in single point threading
A 1mm pitch thread, the Z feed advances 1mm per rev
G33 K1 is the same move as G32 F1 or G95 G1 F1

Try setting:
[RS274NGC]
LAZY_CLOSE = 1
In your ini file.

Hello,
I want to call a subroutine which I have moved to a separate file.
The documentation says this can be done like this:
o call (a named file)
--
myfile.ngc
o sub
...
o endsub
M2
Unfortunately this does not work. Nothing happens when the command
"o call" is executed.

Something I noticed from my own system, is that I have far better performances
in max speed and acceleration when using half-steping on the driver than
full-step.
I've read stories like this on this list too.
Hello Ian,
you didn't state which version of stepconf you are unsing. I spent months
this winter and spring with pretty much the same behaviour you experienced,
and it turned out to be a bug in stepconf, but only when using the "Test
axis" feature. The problem was that the spaces between pulses

In EMC2, K specifies the motion distance per rev in any direction. So
if you're turning a tapered thread yo

I saw a small hexapod in Ger
You might have a 1.8° per step motor which is more common. At least the math
adds up to
that. If you change your steps/rev to 200 I bet your right on.

Wierd. I suspect that something is microstepping somwhere despite
being told not to, or that there
Thanks for the response.
The erratic behaviour appears to be a combination of motor current, step
velocity and stop/start delays.
I read the documentation again..
A lot of fiddling and it is now sitting there repeatedly performing the
same step count.
This stability lets me look at th

The more I think about this, the more sense it is making to me.
"F" controls the speed of travel in the direction of tool movement,
whereas "K" sets the speed explicitly in the Z direction.
