That sounds frustrating, but it's great that it's super repeatable, 
that'll make it easier to find and debug.

I tried to reproduce the problem here this morning in 2.7, but could not 
get anything bad to happen.

Can you reproduce it in a sim config, and send a detailed recipe telling 
me how you reproduce it on your system?

If it's not reproducible in sim, the second best option is to post a 
complete copy of your config (along with the steps you take to reproduce 
the problem) and i'll try to whittle it down to something that i can 
reproduce locally.

It was 2.7.8 and now 2.8.0-pre1-2846-g9e23976, and I can't find a way to 
offer an operator to stop the program in the middle. It just moves after 
stop. Every time.

There were a couple of terrible "surprise move" bugs in 2.7.5 and 2.7.6. 
  As far as we know these are all fixed in 2.7.7 and later.

Which version of LinuxCNC were you running when you had this surprise 
motion?  I really hope it was something older than 2.7.7!

If this problem occurs with 2.7.8, then please try reproduce the problem 
in a sim config.  Then post a tarball of the whole config directory and 
a gcode file and a set of steps the operator can take to reproduce the 
problem.

Well that looks all kinds of broken.  I don't get that when I pause and 
then abort a linear move in 2.7.8 in sim/axis/axis.

This surprise move exists even in the latest master version.

I solved "exception during generator call: TypeError: 'NoneType' object 
is not callable" by deleting and making new python stdglue.py, remap.py 
nd toplevel.py files like it is written here:

Re: [Emc-users] Unexpected move after Stop

[Marius Alksnys]

I can confirm the same on another 3 axis machine with trivial 
kinematics. After stopping or pause/stopping a program motion continues 
some straight line at programmed feedrate to some point and stops. The 
distance is big. This occurs every time, when paused in an arc motion 
and stopped after that. Two tools already broken..

I found this as an already fixed "surprise move bug" in master: 
https://github.com/LinuxCNC/linuxcnc/commit/404be0fd8f6b6396f31943755db4b4754687d79b

Then I installed master branch and get another errors - not being able 
to run any program with an error:
emc/task/emctask.cc 397: interp_error: exception during generator call: 
TypeError: 'NoneType' object is not callable

I also tried to prevent this move to happen with lowering Max Velocity slider

I seem to recall that 5axiskins links to the tool-length offset, so a
change in tool length might change the apparent position of the
controlled point, which the servo loop will attempt to correct.

[Chris Kelley]

Is this a non-trivial kinematics machine?

I'm working on a machine that does something like this when switching
between forward and inverse kinematics (or maybe the other way around). In
my case it is caused by a slight error in my forward kinematics function.
