Mike, i can not agree with you anymore. I have had 3 kits from HobbyCNC.
it ran my 06 for a year and a half, i sold the machine and the controllor and now 2 and 1/2 yrs it is still running. and thats with the 200oz/in motors.
I have the 4 axis pro, and have it hooked to my 4x4 and you can see the video's of it jogging. the board makes the motors run very very smooth compared to some bi-polar drives i have tried.
I hooked up g201's in its place on the same 305oz/in motors (425oz/in in bi-polar and really could not tell a difference, to get the correct performance out of the gecko's i need more than the 36vdc psu i used.
So to me the HobbyCNC Pro kit is the way to go if you do not want to spend for Gecko's and a more expensive PSU.
Don't get me wrong, the gecko's are superior drives, but you will need to run them with more power to take full advantage of them.
