Just popped on ebay and this tb6600 is the one id like to know about. Has anyone used it? Does it do what it says on the tin? If i remember correctly I am hoping to use nema 23 motors 566oz 4nm 4a the specs say it will work so just hoping for someone to tell me its not to good to be true
I've been using that controller on a small 3040 CNC mill for the last couple of years, using MACH3. I found it to be very good - it not only does the control bit but steppers are driven directly without need of extra driver boards. However whether it is meaty enough to handle big steppers as might be found on an 8x4 mill I can't say - mostly I used it to drive steppers which were drawing 1.7A apiece, but latterly upgraded to ones which draw 4A each - it took the hit no problem, though mine was only casual use so maybe it would go pop if I gave it some serious work.

I don't have any big negatives to share about this controller, and would buy another should I ever be looking to provide the functionality.

As for not buying bits as advised by others, I applaud you for taking the piecemeal approach. Buying this box is going to keep you happy fiddling around with configuring it, and I do feel it would be a wise investment to get it early - otherwise if you buy the big kit in one fell swoop you'd have a mountain to climb to get everything working. With this box and just a single stepper and some microswitches you can learn the basics.
