Gen6 & Darwin

Hi there,
For lots of reasons - good and bad ones - I have left a mechanical kit from Bits&Bytes in my garage for 2 years now ... I finally starte building it some months ago and now I'm almost finished with the darwin robot mechanical part. I'll then need to add the electronics and need to make a choice here ... lots of generations have been developped since then (I think Gen2 was just released when I bought the kit ...). I can see that Gen6 seems to be cheaper than the previous ones and I'm not far from the Netherlands. So my question can sound easy like this : is the Gen6 suitable for a Darwin Repstrap ? Any other suggestion ?

cheers
Gad

It should work without a problem - Darwin is still a cartesian bot driven by three NEMA17 steppers, plus an extruder.

Thanks Andrew
The Repstrap I own has 3 x NEMA 23 motors but I guess it makes no change compared to NEMA 17.
The stepper driver inside Gen6 seems to be the DRV8811 and provides 2,5A whereas the motors (FL57STH51-3008 are rated 3.0A, which is not good I guess
However, from the motor spreadsheet (http://www.motioncontrolproducts.com/pdfs/FL57STH51-3008B.pdf), the 3.0A current/phase is in the unipolar configuration whereas the normal Reprap settings are in bipolar. In bipolar, if I understand the spreadsheet correctly, the current/phase is 2.1A, well under the stepper driver current capacity.
I hope I'm right here...

Thanks
Gilles

Even if you had motors spec'd for 5A you could still drive them with 2A drivers. You only get tourque for 2A then, of course.
