OOps, I think you have to change the sign of HOMING_VEL!
Actually, I don't know what the difference between HOMING_VEL
and HOMING_POLARITY is? Maybe HOMING_POLARITY
is the polarity of the index signal from the encoder! I think it is, so
my original info was wrong (But, I was within 4 lines of the problem!)

I know this worked on exactly the same situation at my client's.
