perhaps if you have a shared power supply, it has insufficient reserve power 
to move all the axis at once ? You could use more/bigger supply capacitors or 
a local reservoir capacitor at each drive .If your psu voltage isn't dropping 
it may be a supply resistance problem ? You could use local reservoirs + 
bigger wires on the supply.
Another thought could be your command wires may have to much capacitance 
and the higher speeds are asking too much from your parrallel port card 
supply. you could try better cable (or just to prove it some thin wire pairs 
hand twisted 2t/inch and wired signal/ground for each parport output )
dont forget to check your drive earthing/common, seen a few problems where 
there were seperate power wires but a single common return wire the same 
rating. which would carry the 3 supply currents and lift the ground at the 
drives which would then ground via your parrallel port signal returns !! 

my first post. Is this progress or is everyone dropping to my level
