...when looking for an index pulse, that is. I've not had  problems with
NO_INDEX_PULSE un-commented in /src/emcmot/extstgmot.c .
    The setup i.e. which direction the home went, was a real treat. If I
remember correctly, it had to do with the signed homing offset direction and
motor polarity. (signed velocity might have had a part, too.) I need to go
back and find my notes...

Provided the EMC sources from the BDI are installed on your computer, you
might be able to re-compile the emcmot modules from within
/usr/local/emc/src/emcmot/ using 'make' and specifying the rtlinux flavor
you have. (found in emc/plat)

This has worked for me with the emcmot modules. (not the NML ones...)

/usr/local/emc/src/emcmot/ #> make PLAT=rtlinux3_0

I could upload the stg_v2_8axis module I use, but I've changed the I/O
addresses for the limits and enables to fit a 16IO Grayhill board. (no Index
pulse w/ that...)

Note: I'm using BDI 2.04. Paul has a little script on the handbook pages
which I needed to run first which sets up the necessary kernel
dependencies/headers. I believe this is basically re-'make' ing the kernel,
which generates the headers/dependencies EMC needs. Paul?
