If you are missing steps on the Rutex you will probably have the same
problem on the GECKO G340. The only difference would be the opto
input on the Gecko. If there is noise on the auxillary power supply
ground to the Rutex you could be picking up extra steps but loosing
steps would indicate there is a problem in the Step or Direction
signal from the computer. A buffered breakout card may solve your
problem.

I am running a servo machine with Gecko340's as the dual Y drives and
a H990 as the X axis drive....absolutely no problems with either.
