Hi all, a quick question before making the final decision on stepper drivers for our local FabLab (http://www.avilab.fr) C-Beam build which we plan to make move with OpenBuilds High Torque Series NEMA23 or similar motors (3A+): Wantai DQ542MA or Chuanwei CW5045 ? Or any other best suited/higher quality/best performing for these motors ? (electronics will be arduino+cnc shield)
Another one, I think I’ve red somewhere that they where digital drivers but tech specs make me doubtful 
Could someone clarify this for me please ?
wantai. i use them for the past 6 months with no problems
Hi Jeremie
The CNC shield may only power up to 1.2 A. Please check.
@Brad_Cahoon thanks for the warning but I think the CNC shield has control pins to drive external drivers 
@Alex_Paverman thanks for your feedback
Which CNC shield, if you are using external drivers just pin it to the arduino. I have the CNC shield v3 but stopped using it because I have 2.5A steppers. I will post picture of my setup tomorrow.
@Brad_Cahoon that’d be really helpful. Thank you in advance !
What the inductance of those motors?
