Two things:
1) This method of control is against the "NIST principle" regarding 
multiple locus of control.  What that means is that since there are 
multiple places from which you can control the feed override (on the 
AXIS screen and the halui knob at minimum), neither place can be an 
absolute setpoint.  Consider this - how will you cause the knob to move 
if the keys or slider in AXIS are manipulated?  If the two (or more) 
user interfaces have different absolute setpoints, how should EMC choose 
which one to honor?  How does the operator know which one is active?

2) At the moment, I don't think there's any way of pre-setting the 
value.  The spindle override value is not an input to halui (since that 
would violate the NIST principle).
