NEMA17:
Please take a look at my last reply, I edited it (again). If the driver is compatible with that stepper I will buy that one and test it with the prototype to be sure about the needed torque/speed.
Like @vincherman said - put new material in an new Reply to maintain the flow of the discussion.
If you are asking about using a 2.8 amp motor with a TB65XX based driver then it seems to me you are not allowing yourself enough headroom. I would always look for a driver that could provide 50% or even 100% more current than my motor needs.
