That will help clarify my thinking, a bunch. So I can use 00 for 
independent vars.

Somebody should fix the docs, it say it needs a move to activate it.  The 
way the peck is written the next move is the next g33.1 and thats too 
late. Thats why I added the .002 moves, so motion would have something 
to do.

Its also too late.

Ok, but what about the docs saying its waiting for input, which I'd 
normally assume will be zero before the first peck, aka no 
data=0.0000000 until the measurement arrives shortly after the bottom of 
the pecks turnaround? And is held valid until the next peck updates it.

Ok, I should be able to get this part working in the morning.

But I just thought of another roadblock, units.py, I need its output to 
make things imperial that started imperial. units.py is apparently 
called from the system as it is not in a loadrt or addf statement 
anywhere. It used like this in postgui.hal
net     display-mode    <= units.G21 => ovrtrvl-scaler-mux.sel
However, a bit of conditional gcode in the ngc file can make a substitute 
for that I think. I was amazed that there is no units loadable module 
when I started this project over a year ago.

Good night & stay safe.
