Yes, and may explain my difficulty in actually using my homing gauge on the 
lathe to establish X=0.000 as the exact centerline.  I adjust it by 5 or 10 
thou, looking to see if the error is reduced, but the new error seems to 
bear only a same ballpark connection with HOME to HOME consistency but 
remaining error being almost a dice roll, almost as if its picking a random 
chance of a - sign in front of the offset stated in the .ini file.  If I 
use NO_FORCE_HOMING=1 and position.txt, it does however seem to restore on 
restart to consistent positions in the gui's DRO.  The machine doesn't 
move, no hand knobs to move it with, so only the drivers power up to its 
electronic home state, which can be as much as half a full step from where 
it was sitting at power off.  Not a huge error, but random.

It could also be that I do not properly understand the explanations in the 
HOMING section of the user manual.  There does seem to me, to at least be a 
possibility of some ambiguity.

Cheers, Gene
