But, Mach2 doesn't actually USE the encoder information, except to
display it on the screen. If a motor stalls and it is a whole inch out of
position, it pays no attention, just displays where the machine actually
is, while blindly continuing to ruin the workpiece. What's the purpose
of encoder feedback, if not to keep track of machine position?
