Anyone have any ideas how to help this guy? 

He is trying to set up a software stepgen to control a spindle that was once 
controlled by a Mach3 config. 
It is sort of working, but the stepgen in Linuxcnc is not creating a steady 
pulse stream. It is sending out clumps of pulses at a steady interval rather 
than a smooth constand stream. (kind of like a badly tuned PID loop) 
But this has no loop, just a constant velocity command.

I've been trying to help him, but I am kind of at a loss for what could be the 
real source of this problem. 

Maybe there is a better way to do this than using the software stepgen 
component?
