Dave,
Good to hear from you! For those following diarmaids HobbyCNC Pro assembly thread, could you enlighten us with the features and benefits of the NEW PRO driver board over the original HobbyCNC 4AUPC driver board. What, if any, performance gains in speed or torque, stability, etc. would someone expect to see when comparing the original HobbyCNC 4AUPC board to the New HobbyCNC Pro board, given the same set of unipolar stepper motors?
Oh, and the new board is ROHS compliant, too, which, if I'm not mistaken is one of the (many) reasons that diarmaid purchased from HobbyCNC (seeing that he resides in Ireland).
Judging from the many posts on this, and other forums, the Sanken/Allegro SLA7062M driver chips are very susceptible to a catastrophic failure. In the driver chips defense, it is usually a mistake on the part of the operator that causes the failure. Are the new chips that you are using on the HobbyCNC Pro board just as prone to user error or are they more forgiving?
Thanks!!!
