Well, EMC2 is also rock solid. I've been using EMC since 1998, and EMC2
since it
came out. I have NEVER had a crash, lockup or abnormal behavior that
could be traced
to the software since 1999 or so. I use it on my production servo
Bridgeport to make
some of my EMC-related products.

No, not at all necessary. My PPMC interface starts at $780 for a 4-axis
system, and includes
essentially everything to interface the entire machine, assuming the
servo amps are
good, and the encoders provide digital output, as opposed to analog.
That breaks down
to $260/axis, assuming you only want 3 axes.

If your amps are shot, then a better choice is my PWM system, a 3-axis
setup is
$250 for the 4-axis controller and $125 per axis for the servo amps.
That is
$625 or $208/axis.

And, every time you E-stop, you have to re-home the machine. With
either of my systems,
you can go to E-stop any time, such as when changing tools, and never
lose the axis
alignment.
