You define the 4th axis as 200 pulses per linear mm while the others are 
set to 80 ppmm.  This will make the pulse binning routines work somewhat 
harder.  I was able to make your ini run okay on a 150 mhz P2 here 
although the display was slow.   Not long ago, a user had a similar 
problem with a 133 processor.

You set an axis in motion at 15 mm per minute and watch for the home 
switch.  That axis does not stop instantly when home is found so it is 
beyond home when it stops.  It will move back to the home position or to 
the HOME_OFFSET beginning on the next motion loop but the MIN_LIMIT   and 
MAX_LIMIT  are tested during this time.  You need to add some little 
distance for this over travel in the MIN_LIMIT or MAX_LIMIT direction.

I think that the amount of distance to add is related to the speed the 
axis is traveling during home,  the deceleration that has to be applied, 
the motion loop frequency, and the number of pulses per unit.
