newstgmod.o is compiled from a rewrite of the ServoToGo driver. It should work with
both model I and model II cards as well as both 4 axis and 8 axis cards and it fixes a problem with
the index pulse latching in the older model II driver but its a relatively recent edition and only 
tested on one machine( on which 4 axis model I and model II cards were swapped in and out). It 
includes code from servo to go to query the board to determine if its a 4 axis or 8 axis board but 
since I only had the two 4 axis boards working and available at the moment. I'd feel more confident 
about it if someone would test it with an 8 axis board.


The other possibility is to compile the older stg2.c with the -DSTG_8_AXES flag.

to do this

cd emc/src/emcmot

make PLAT=rtlinux_?? LOCAL_CFLAGS=-DSTG_8_AXES clean stg2mod

(replace ?? with rtlinux version i.e rtlinux_3_0)

Then use stg2mod.o now built for 8 axes.
