That means expanding an already too darned big pyvcp panel to make the 
buttons. And I already have plans to add an overshoot tally in spindle 
turns at the point of the reversal at the bottom of a peck stroke while 
rigid tapping. That will use up 1/2" of additional space thats already 
being overwritten by prompt or error msgs. Its also more coding than the 
hardware approach. I have that working well on the lathe, but it only 
has one spindle encoder scale, whereas I have to scale for the backgear 
in use on the mill where this would also be used. The question is, which 
is more important information wise.

I also need to find an ammeter to put in series with the spindle motor so 
I can more easily determine when its time to put it in low gear as I'm 
getting too close to its torque ability in high gear.  Needs to have a 
fs reading of perhaps 20 amps. But that is another "nice to have" 
item. :) Analog of course, digital's won't catch the peaks.

Thanks Andy. I may be back to carving xml code yet.
