Motor class doesn't have the ability to accurately brake after it moves the specified distance. about nxt-python HOT 11 CLOSED

Braking is handled automatically by the firmware. All that is needed is a simple
tweak of the command sent to the NXT. See the docs on the NXTreme website for 
details.

No, I tried setting the mode to BRAKE, and it didn't stop the motor, it just 
made it 
coast...

Looks like I was incorrect. You managed to get braking working just fine with 
that patch.

I am experimenting with the best way to use the "examples" you provided to 
implement
stopping after a certain distance, and am having much better luck now, thanks :)

The current solution seems to work well enough, though a better one would be 
nice.

There is a brick-based program which will do exactly what we want. It is called
MotorControl and is available (with docs) here:
http://www.mindstorms.rwth-aachen.de/trac/wiki/MotorControl
While I don't have time to implement it right now, I think that it is a good 
idea and
should be experimented with if possible. The current functions of the library 
are
enough to be able to use it in a program, but this may not be the most 
user-friendly
solution.

Just to give an update, there is improved code for this in the tubes for 
version 2.
rhn made it and while I have not tested it, I hear it is better than anything 
so far.

I have tested the v2 motor code and find it to be very accurate (within about 5 
degrees) when using USB and less accurate but still usable (within 60 degrees) 
on bluetooth. As I believe that the performance can't get any better than this, 
I am going to close this issue.

Thanks very much to everyone who helped out with this!
