I'm a bit confused, at first you want to use it because its faster better, then you say your not concerned about speed or acceleration... I'm missing something..
I would think for a simple system which has no concerns for acceleration and torque that you'd be more interested in a standard BOB. The Grex really only shines for two reason's, #1 it has more I/o and options in that regard [spindle control etc] and it can utilize a fantastic resolution [4Mhz step rate]
[well three if you can use the self program function of the unit and run it as an independant control]
If neither of these two are important, then faster, better, whatever aren't really a concern, as far as KISS, there isn't anything simpler than a $300PC and a $120BOB, the Grex is $400 PLUS the price of a PC, that or you program it yourself, now for each new function you want it to do, your going to have to write a new program.. in my books.. thats not KISS.
Some of these questions would probably be better address to Mariss on the Yahoo Geckodrive weblist. Mariss is the "Father" of the Grex and if he doesn't have the answer's.. ain't no-body got the answers

In the end you are more then likely right, I was hopeful that I could do it that way. I have not put a ton of thought into this yet, I was more trying to get some basic answers first, see what it can do etc. I will more then likely stick my current plan and use a BOB and a PLC or just a PLC.
thanks for puttin me in the right direction.
